In 2021, the sports world continued to grapple with fast-changing pandemic circumstances.
The first months of 2021 saw many professional athletes test positive for COVID-19, causing disruption to league schedules and major events. Events that continued, such as the Australian Open tennis tournament, were held under strict COVID protocols and restrictions on fan attendance. By March, increased availability of COVID vaccines in places such as the United States saw some professional leagues incentivize vaccination by loosening COVID restrictions for vaccinated players. WNBA players showed remarkable leadership in achieving a 99% vaccination rate and supporting community vaccination efforts. Other pro leagues also had high levels of vaccine uptake; yet some superstar athletes, including NFL quarterback Aaron Rodgers and NBA guard Kyrie Irving made headlines for their refusal to get vaccinated. Meanwhile, media also start reporting on athletes experiencing long-term effects of COVID infection.
The postponed 2020 Tokyo Summer Olympics and Paralympics were staged amid controversy as COVID cases rose rapidly across Japan. As the Japanese government responded to these high case numbers by declaring a state of emergency, the Games were held in a “closed-loop” bubble system designed to prevent any interaction between Olympic participants and Tokyo residents. Olympic organizers declared the Games a resounding success, touting their efforts as a model for holding mega-events in pandemic times.
The waning dominance of the Delta variant through September and October saw case numbers decrease in many places and sports fans (often masked and vaccinated) returning to full capacity stadiums. However, the rise of the Omicron variant in late 2021 interrupted any hope of a quick return to normalcy as a rising wave of infection impacted professional leagues and led to the cancellation of several major sporting events.

NBA players test positive
Two weeks into the NBA season, four players test positive for COVID-19 – including Philadelphia’s Seth Curry and Boston’s Jayson Tatum. Many other players are forced to miss games as league health and safety protocols require anyone exposed to a COVID-positive individual to isolate until they receive medical clearance. These protocols have led to teams playing with severely shorthanded rosters and four games were postponed within an already compressed schedule. The NBA responds to these developments by tightening COVID-protocols.
The new rules require players to avoid activities “outside of the team environment,” staying confined to team hotels on road trips, and limiting social interactions to members of their household. George Hill of the Oklahoma City Thunder criticizes the new rules, saying “If [COVID is] that serious, then maybe we shouldn’t be playing. But it’s life; no one’s going to be able to just cancel their whole life for this game.” 61-year-old New Orleans Pelicans head coach Stan van Gundy comments that the heightened risk of COVID-19 infection brought on by the NBA season “scares” him.

Players arrive for Australian Open
As players, coaches, and staff fly in to Melbourne in advance of February’s Australian Open tennis tournament, intake testing reveals several positive COVID cases. Australia had been successful limiting the spread of COVID-19 throughout the country enforcing strict restrictions on international travel and quarantine rules. The Australian government set up what they called “the tightest quarantine arrangements in the world for a tennis tournament” to limit the Open’s impact on national COVID cases.
All players arriving in Australia are required to quarantine for 14 days at designated hotels and would only be allowed outside their rooms for 5 hours a day to train. However, players who were on flights with individuals who tested positive upon arrival would be subject to a period of “hard” quarantine for which they would not be able to leave their hotel rooms.
These extra restrictions sparked concerns about the competitive disadvantages faced by players unable to leave their rooms; Swiss player Belinda Bencic, the #12 ranked player in the world, tweeted, “We are not complaining to be in quarantine. We are complaining because of unequal practice/playing conditions before quite important tournaments.” Players under hard quarantine were forced to find creative ways to train while confined to their rooms, but still faced psychological difficulties; Ukrainian player Marta Kostyuk lamented during her isolation period that “being alone is such torture”.
These concerns coincided with existing tensions around player accommodations. Six of the world’s top players – Serena Williams, Naomi Osaka, Simona Halep, Novak Djokovic, Dominic Thiem, and Rafael Nadal – were scheduled to play at a pre-Open exhibition tournament in Adelaide and were allowed greater freedom at their designated hotel. Jérémy Chardy, a French player ranked #66 in the world, criticized this discrepancy, saying, “They will almost be able to live normally. Already they have a lot of privileges. If they can do everything more than you, it will not be the same preparation. And that’s weird for a sport where we’re all supposed to be on the same footing.”

Summer Olympics and Paralympics to proceed
With COVID cases surging nationwide, Japanese Prime Minister Yoshihide Suga publicly vows that the postponed 2020 Tokyo Summer Olympic and Paralympic Games will proceed as planned in July and August. Suga asserts that the Games will represent “proof of human victory against the coronavirus” and a symbol of “hope and courage throughout the world.” He touts planned “anti-infection measures” as guaranteeing the success of the Games and calls forthcoming vaccines as the “clincher” that will bring about the end of the pandemic.

Gymnastics championships re-located
USA Gymnastics announces that the 2021 Senior Pan-American Championships will no longer take place in the United States. The organization released a statement saying, “after assessing all COVID-related risks and requirements, officials determined that it would not be in the best interests of all participating athletes for the event to be held in the U.S.” The Championships, which were already postponed from May 2020, would be moved to Rio de Janeiro, Brazil and held from June 4-13.

Serena and Nadal commend Aussie Open protocols
Serena Williams and Rafael Nadal praise the protocols put in place at the Australian Open. On The Late Show with Stephen Colbert, Williams describes the restrictions as “super, super strict, but it’s really good. They’re doing it right.” Nadal asks quarantined players to put their experiences in perspective, saying “I feel very sorry for all of them, but when we came here, we knew that the measures were going to be strict because we knew that the country is doing great with the pandemic. It’s normal to complain…but on the other hand, you see how many are dying around the world. You see how many people are losing their father, their mom, without having the chance to say goodbye.”

No more fans at Australian Open
After the tournament hosted spectators for the opening three rounds, fans will not be allowed to attend Australian Open matches in compliance with a five-day state-wide lockdown. The lockdown was instituted in response to the detection of the new, “hyper-infectious UK variant” (Alpha B.1.1.7) among positive cases at a Melbourne hotel. Victoria Premier Daniel Andrews explains that “Large and small professional sport events, they will function essentially as a workplace. But they will not function as an entertainment event, because there will be no crowds.” Fans are subsequently allowed to return to the Open for the semi-final and final matches.

NHL games postponed due to widespread outbreaks
A month into the NHL season, 35 games have been postponed due to COVID outbreaks. These cancellations have all involved American teams; the Northern Division, which includes the league’s six Canadian teams, has yet to postpone any games. While league protocols are identical for teams in both countries, experts hypothesize that relatively tighter government restrictions in Canada have likely protected players from community exposure to the virus.

College basketball player has myocarditis
Demi Washington, a player for the Vanderbilt women’s basketball team (NCAA), is found to have myocarditis following her recent COVID infection. Washington had completed all Atlantic Coast Conference (ACC) medical testing protocols to return to play after COVID infection, but the Vanderbilt athletic department also required athletes to undergo a cardiac MRI before they are cleared to return. It was this additional step that identified Washington’s myocarditis and prevented her from returning to play with a dangerous heart condition. Washington says, “I know myself. If I was back on the court and my heart was pounding, I would’ve pushed through it. I would have thought I was just out of shape and needed to go harder. This has all been a learning experience and, moving forward, I will have a better awareness.”
Her story is portrayed alongside research published by the Vanderbilt University Medical Center that compared athletes who developed myocarditis post-COVID and a healthy athlete control group. The study shows that 27% of the COVID athlete group had scarring in the heart muscle compared to 24% in the control group. The imaging demonstrated, however, that myocarditis after COVID-19 tends to be located in a similar part of the heart, which could help distinguish it from scarring unrelated to COVID infection. Sean Hughes, co-senior author on the study, notes that their results suggest that “myocarditis after recovery from COVID-19 is less common in athletes than we had feared.”

Djokovic wins men’s Australian Open; will ‘wait and see’ on vaccine
Novak Djokovic wins the men’s final at the Australian Open. During the trophy presentation ceremony, Tennis Australia official Jayne Hrdlicka is booed by a group of Djokovic’s fans when she mentions the introduction of COVID vaccines as providing “hope for the future” after a “a time of deep loss and extraordinary sacrifice.” Djokovic had previously said that he opposed vaccines, including for the coronavirus.
The men’s Association of Tennis Professionals (ATP) had stated publicly that they were considering making vaccines mandatory to participate in tour events. When reporters ask him if he’d get vaccinated to comply with a tour-wide mandate, Djokovic says he is taking a “wait and see” approach.

Olympics/Paralympics COVID protocols released
The International Olympic Committee (IOC) releases its COVID “Playbooks,” a set of protocols to promote the health and safety of athletes, officials, media members and workers throughout the Olympic and Paralympic Games. Requirements include a strict regime of testing, temperature checks, and contact tracing, but vaccination will not be mandatory. The IOC states that they strongly encourage athletes to get vaccinated when vaccines are available in their home countries. Updated versions of the Playbooks are published in April and June that respond to developments in the trajectory of the pandemic.

Athlete post-COVID heart health study published in JAMA
A new study of the prevalence of inflammatory heart disease among professional athletes is published in the Cardiology section of the Journal of the American Medical Association (JAMA). The research was conducted through a collaboration of medical experts from MLB, MLS, NBA, NHL, NFL, and WNBA. The study involved comparing results from each league’s cardiac screening program for athletes who had recovered from COVID-19 infection. Study findings are encouraging: out of 789 COVID-19 positive athletes from across the leagues, evidence of inflammatory heart disease was identified in 0.6% of athletes screened.
The study also details how no adverse cardiac events were recorded among athletes who underwent cardiac screening and subsequently returned to work. A joint statement on behalf of the six leagues reads, “As with other lessons professional sports have learned about COVID-19, the results of this study are being shared broadly to continue to contribute to the growing body of knowledge about the virus.”

NBA announces incentives for vaccinated players
As doses of COVID vaccine become more available across the United States, attention turns to how soon professional athletes will have the opportunity to be vaccinated. The NBA announces incentives for teams with high rates of vaccination: when a team reaches an 85% vaccination rate, vaccinated players will be tested less frequently, will no longer be required to wear masks at team facilities, and be subject to fewer restrictions related to socializing and public mobility (e.g., eating in restaurants, leaving team hotels on road trips). The New Orleans Pelicans are the first team to confirm that they have launched a team-wide vaccination effort.
Some NBA players hesitant to get vaccinated
Reports in the coming weeks depict many players as hesitant to receive the vaccine or at least reluctant to publicly discuss their vaccination status. When asked by reporters if he would be getting vaccinated, LeBron James responded, “That’s a conversation that my family and I will have. Pretty much keep that to a private thing.” Other players expressed outright opposition to vaccination, such as Golden State’s Andrew Wiggins, who affirmed, “I don’t really see myself getting it any time soon, unless I’m forced to.”

Inequities revealed at NCAA basketball tournaments
As the popular March Madness tournaments are set to begin, the NCAA faces criticism for inequities within the conditions for men’s and women’s players. Viral social media posts document how women’s teams have been afforded inferior weight rooms and fitness facilities, subpar food amenities, and less tournament merchandise compared to the men’s side.
University of Connecticut women’s coach Geno Auriemma tells reporters that these discrepancies extend to the COVID-testing technologies available for men’s and women’s teams with testing in the men’s tournament using “gold standard” PCR tests whereas the women’s event is using less reliable Rapid Antigen tests.
These reports describe how PCR tests are considered the “gold standard” technology since they “actually detect RNA (or genetic material) that is specific to the virus and can detect the virus within days of infection, even for those who have no symptoms.” Rapid Antigen tests, which offer quicker turnaround times than PCR tests but are more likely to miss active infections – especially those that are asymptomatic.
NCAA President Mark Emmert responds to the criticism by saying, “I’m not a medical expert so not going to get into a debate about PCR and antigen. All the health experts said the protocol that we’re using in all of our venues and all of our championships has no difference at all in terms of our ability to mitigate risk.” Yet investigations later suspect that the rapid tests produced many false positive tests at the women’s tournament: 226 positive tests were recorded without any other evidence of COVID transmission. This meant that some players had to miss tournament events while they waited for further testing – a problem not encountered on the men’s side.
The inequities across the men’s and women’s tournaments spark a months-long review, culminating in a 118-page report detailing recommendations for addressing these gender inequities.
March 29
MLB announce vaccine incentives
Two days before their league’s Opening Day, Major League Baseball announces their own set of incentives to promote vaccination across team rosters. Many players across the league have already expressed that they are hesitant to get vaccinated. New York Mets third baseman J.D. Davis states that getting vaccinated “hasn’t really crossed [his] mind” and that he and his teammates are unlikely to be persuaded by MLB’s announced incentives. Washington Nationals pitcher Max Scherzer, in contrast, says. “I try to listen to what all the scientists say and what the experts say. I see the benefit of it. Can’t wait to get it.” Four members of the Milwaukee Brewers (Christian Yelich, Keston Hiura, Freddy Peralta and Brent Suter appear in a Wisconsin Public Health PSA encouraging all adults to receive the vaccine.

MLB Season Begins
The Major League Baseball season begins with visible differences in fan attendance at different stadiums. In states where robust COVID protocols remain in place, such as New York and California, stadiums are subject to greatly reduced capacities and fans must present proof of vaccination or proof of a negative test to enter. Most spectators at these outdoor venues are also seen wearing masks as an added layer of protection. These images stand in stark contrast to those of a packed Globe Life Stadium, the home of the Texas Rangers. The lack of state-wide pandemic restrictions allowed the stadium to be at its full capacity of 38,000 for Opening Day. President Joe Biden called the Rangers’ decision “a mistake” and “not responsible” as it defied public health guidance from the CDC.
Meanwhile, due to U.S./Canada pandemic border travel restrictions, the Toronto Blue Jays will play their home games at their Spring Training facility in Dunedin, Florida. Blue Jays management says that the team will then relocate in May or June to the home of their AAA affiliate in Buffalo, New York.

NHL’s Canucks experience team-wide outbreak
The NHL’s Vancouver Canucks announce that 17 of its 22 active players have tested positive for COVID going back to March 30. This represents the league’s largest outbreak and is reportedly linked to the new P1 variant first identified in Brazil and widely circulating in the Vancouver Area. Sources detail how many Canucks players are in “rough shape” with severe fatigue and dehydration. Ten Canucks games between March 31 and April 17 are postponed while the players recover.
Forward Jayce Hawryluk tests positive for the second time after contracting the virus in 2020. He describes how it took months to “feel like himself again” after his first COVID diagnosis and calls the current outbreak “a scary time.” Other media stories detail the mental health impacts of the outbreak on players and their families.
Brandon Sutter was another one of the Canucks players who became infected during this outbreak. Sutter experienced severe symptoms but was able to return to play the remainder of the season. His COVID symptoms returned throughout the subsequent off-season, however, and his challenges with Long-COVID forced him to retire in 2023 after multiple comeback attempts.

NHL will not offer players vaccine incentives given high compliance
Reports indicate that the NHL is unlikely to offer incentives to promote vaccination as the vast majority of players say they are amenable to being vaccinated.
Yet the Canucks outbreak had revealed how multinational sports leagues must contend with varying levels of vaccine access in different countries. As the United States was able to manufacture an ample supply of vaccine for its citizens, Canada does not have the production capacities and is forced to rely on the global supply chain. Thus, while U.S.-based NHL teams have been able to offer opportunities for players to get vaccinated, player on Canadian teams have to wait for public health authorities to expand vaccine availability beyond priority populations.

Soccer star Leroux’s social media post details her children’s severe COVID infections
U.S. Women’s National Soccer Team star Sydney Leroux posted to Instagram describing her children’s severe COVID symptoms. Leroux, who also plays for the NWSL’s Orlando Pride, explained that her 4-year-old son and 21-months-old daughter had experienced harsh fevers, exhaustion, and vomiting. Leroux ends her post by refuting the notion that children cannot be impacted by COVID-19 infection, saying, “It has been an extremely hard couple of weeks, but thankfully things are much better now. I wanted to share this story to urge everyone to continue taking this virus seriously, when it comes to both you AND your children.”

NCAA men’s March Madness wraps up; linked to two COVID deaths
At the conclusion of the NCAA men’s March Madness tournament held in Indianapolis, Indiana, officials call the event a resounding success. The tournament was held entirely in Indianapolis (instead of its traditional format of being spread across multiple cities) and used a bubble system with COVID safety protocols in place (including testing, isolated accommodations, restricting interactions with individuals outside of the team environment, limiting fans to 25% capacity).
Indianapolis Mayor Joe Hogsett say that the city has “proved to the world that we can responsibly host major events.” Dan Gavitt, NCAA Senior Vice President of Basketball, similarly praised Indianapolis for meeting the challenge of putting on a major sporting event during a pandemic. Gavitt highlights that out of approximately 28,000 COVID tests of participating players, coaches, and team staff, only 15 (~0.0005%) came back positive.
Yet the tournament also concludes in the shadow of the deaths of two men, Luke Ratliff and Michael Gaines, who both died from COVID infections possibly linked to the tournament.
Ratliff, a 23-year-old student at the University of Alabama had traveled to Indianapolis to attend an Alabama tournament game and died in hospital after returning home to Alabama. Research following the tournament indicated that less than 75% of spectators at tournament games complied with masking requirements. Gaines, a bartender at an Indianapolis restaurant popular with tourists, died in the midst of a COVID outbreak among the restaurant’s employees. In the aftermath of Gaines’ death, the Indianapolis Star reports that hospitality workers felt they were not prioritized in public health efforts around the tournament (in contrast to stadium workers or tournament personnel) even though fans attending games would be staying in hotels and visiting restaurants or nightclubs.
Subsequent research published in October also shows that gatherings to watch tournament games on university campuses likely contributed to increased COVID infection rates in those places.

NBA partners with digital security firm CLEAR
The NBA announces a partnership with CLEAR, makers of “secure identity platforms,” for use of their Health Pass app at league arenas. The app “securely connects a user’s verified identity to multiple layers of COVID-19-related health information” such as test results or vaccine information. The league states that a third of all teams have already implemented the technology for their employee or fan COVID protocols.

NFL urges teams to promote vaccination; players question safety protocols
The NFL releases a memo encourage teams to promote vaccination and provide opportunities for all players and employees to get vaccinated at team facilities. Higher level employees who have regular contact with players are expected to be vaccinated unless they have “a bona fide medical or religious ground for not doing so.” Any employee who is not vaccinated with not be permitted to work in close proximity with players.
The memo also states that the league plans to hold voluntary offseason workouts with enhanced health and safety measures in place. The NFL Players Union calls for all offseason training programs to be held virtually to protect players. This demand comes after members of the Denver Broncos announced that they are “exercising their right to not participate in voluntary offseason workouts” on the grounds that “COVID-19 remains a serious threat to our families and our communities.” Seattle Seahawks and Tampa Bay Buccaneers players also state that they will not be reporting to scheduled voluntary training programs.

NFL’s Bills announce use of vaccine passport for fans
The Buffalo Bills become the first NFL team to announce they will be using a vaccine passport system at their home games. Requiring proof of vaccination at the stadium will allow for the Bills to play games at full stadium capacity. Erie Country Executive Mark Poloncarz explains at a news conference that being a spectator at a sporting event is a choice and a privilege that can be taken away under certain circumstances, saying, “there is no God-given right to attend a football game.”

WNBA PSA promotes vaccination
The WNBA release a public service announcement promoting COVID vaccination called “Our Health is Worth a ‘Shot’”. The 30-second video features players Layshia Clarendon, Nneka Ogwumike, Elizabeth Williams, and A’ja Wilson who “shine a light on health inequities experienced by communities of color and the significant impacts of COVID-19 specifically on Black women and girls.”

Women’s Hockey Worlds canceled for second straight year
The Women’s World Hockey Championship is canceled for the second year in a row only two weeks before the event is scheduled to begin. The tournament was to be hosted in Halifax and Truro, Nova Scotia. The cancellation was prompted by Nova Scotia public health authorities re-instating restrictions on travel into the province in response to new variants of concern and rising COVID numbers across Canada. The new rules only allow non-essential visitors from two neighboring provinces with low COVID rates: Prince Edward Island and Newfoundland & Labrador.
Truro mayor Bill Mills says regarding the tournament’s cancelation, “I think it’s the right decision, as much as I don’t like it.” René Fasel, president of the International Ice Hockey Federation, expresses frustration in a statement, writing, “This is very disappointing news to receive with just a few weeks until the tournament was to begin. We strongly believe that we had the adequate safety measures in place to protect players, officials, spectators, and all residents in Halifax and Truro…”

Pfizer will donate vaccine doses for Tokyo Olympics
Pfizer and BioNTech announce that they will provide doses of vaccine to the International Olympic Committee to help vaccination efforts among athletes and their national delegations. IOC president Thomas Bach describes the donation as “another tool in our toolbox of measures to help make the Olympic and Paralympic Games Tokyo 2020 safe and secure for all participants and to show solidarity with our gracious Japanese hosts.”

WNBA’s Durr missing second season in a row with Long COVID
A.D. Durr of the WNBA’s New York Liberty is placed on the team’s full-season suspended list as they will miss a second consecutive season due to long-term effects of their June 2020 COVID infection. In January, A.D. told HBO’s Real Sports, “I haven’t been able to [practice basketball]…I’m not cleared to be able to do anything physically, which could cause flare-ups. I can’t even shoot a free throw.” They say that they have lost 32 pounds since they had COVID and that “There’s days where I feel great, like I could go out and go to the store or I could clean up. And then there’s days where I’m like, ‘I just have to stay in the bed,’ and you just feel like you got hit by a bus.”

Yankees outbreak raises questions about “breakthrough” infections
New York Yankees shortstop Gleyber Torres tests positive for COVID-19 becoming the first player to contract the virus during the team’s current outbreak. Seven other members of the organization, including coaches and support staff, had recently tested positive. These individuals had all been vaccinated at the beginning of the season, which provoked some concern about the effectiveness of vaccines.
Scientists respond by affirming that such “breakthrough infections” among vaccinated people are expected since the vaccines do not offer complete protection against infection. The Johnson & Johnson vaccine used by the Yankees is believed to be 100% effective in preventing severe illness and death, and between 66 and 72% effective at preventing infection. Other experts use the Yankees outbreak as an opportunity to offer education around different types of COVID tests and variances in viral load during infection.
WNBA Documentary ‘144’ debuts
The ESPN Films documentary tells the story of the 2020 WNBA “Wubble” season in Bradenton, Florida. It focuses on the challenges and successes of this “bubble” season, especially the players’ social activism in the wake of nationwide protests against police brutality.

CDC updates guidelines on masking
The U.S. Center for Disease Control issues new guidance stipulating that those who have received two doses of vaccine are safe to stop wearing masks in public spaces. While local and state regulations still ultimately determine the enforcement of mask mandates in different parts of the country, the new federal guidance offers opportunities for other jurisdictions to relax their rules. CDC Director Dr. Rochelle Walensky tells reporters, “We have all longed for this moment, when we can get back to some sense of normalcy.” The CDC is both praised and criticized for their decision, with critics pointing to uneven levels of vaccination across the country and the possibility of “breakthrough” infections among vaccinated people.
Commentators suggest that the updated guidance will be “good news” for the sports industry that is seeking to have stadium capacity restrictions relaxed and further encourage fans to return to live events. A few days later, New York governor Andrew Cuomo announces that the NBA’s New York Knicks and Brooklyn Nets can have 50% of their arenas reserved for vaccinated fans who will not have to wear masks.

Poll shows opposition to Olympics across Japan
A national poll suggests that 80% of Japanese people oppose hosting the Olympics this year. 43% of those surveyed want the Games canceled altogether while 40% of respondents prefer further postponement. The poll results come with only 10 weeks left until the start of the Games and Japan under an expanded state of emergency amid a nationwide COVID surge. The resurgent spike in COVID infections has placed the nation’s healthcare system under stress with mounting concerns about healthcare staff shortages and physician burnout.

Positive test forces Rahm to withdraw from PGA’s The Memorial
Golfer Jon Rahm tests positive for COVID in the middle of the PGA’s The Memorial tournament and has to withdraw while leading by 6 strokes in the third round. Rahm, the tournament’s defending champion and number two ranked player in the world, was already enlisted in PGA COVID protocols having been exposed to a COVID-positive person before the tournament started. He had tested negative throughout the week until his routine Friday test turned up a positive result on Saturday. Rahm said in a statement, “I’m very disappointed in having to withdraw from the Memorial Tournament. This is one of those things that happens in life, one of those moments where how we respond to a setback defines us as people.”

Cubs’ Rizzo announces he is not vaccinated
Chicago Cubs first baseman Anthony Rizzo receives backlash for announcing that he has not been vaccinated. The Cubs had already drawn criticism for being one of the eight MLB teams to not reach the 85% vaccinated mark that would qualify them for league incentives. Rizzo explains that his refusal of the vaccine is a life decision” made for “personal reasons” and that he supports people getting the vaccine. He says, “there are a lot of lives that are being saved by this vaccine” but he was “taking more time to see the data” before making a final decision.
Rizzo’s teammate Javier Báez, who publicly promoted getting vaccinated, supports Rizzo’s decision, saying “Everyone feels different, and they just don’t believe in it right now. We respect his decision…We know who the people are who are not (vaccinated). We respect him.”

NBA’s Chris Paul enters quarantine before conference finals
Phoenix Suns all-star Chris Paul enters NBA Health and Safety protocols days before the Suns are scheduled to begin the Western Conference Finals. Questions swirl around Paul’s status: did he test positive for COVID or was he quarantining after exposure to a COVID-positive individual? Is he vaccinated?
Paul has to this point refused to publicly declare whether he is vaccinated, calling the decision a “private matter.” With Paul leading the Suns on an exciting playoff run, his potential absence from the Conference Finals causes immense disappointment around the league; Slate magazine asserts in a headline that “Chris Paul’s COVID Absence Threatens the Playoffs’ Most Thrilling Storyline”.

WNBA reaches 99% vaccination rate following player-led initiatives
Only one month into their 2021 season, the WNBA announces that 99% of the league’s players are vaccinated against COVID-19 with all 12 teams meeting the threshold for a “fully-vaccinated” designation under league rules. The CDC applauds the Women’s National Basketball Players Association for their “impressive milestone,” which was achieved through player-led initiatives. These included facilitating open-ended education sessions with racially diverse medical experts during which players could ask questions and engage in conversations with other participants.
WNBPA executive director Terri Jackson explains that union leadership invited experts from multiple medical and scientific disciplines: epidemiology, researchers connected to the vaccine clinical trials, obstetricians, mental health specialists, and those with experience navigating Black and Brown communities’ historical mistrust in medical institutions. This was done with sensitivity to the league’s diverse population, which is comprised of women and non-binary individuals of different races, ethnicities, and sexualities. Some players are mothers or were interested in knowing how the vaccine might impact future pregnancies. USA Today asserts that the WNBA “put the NBA to shame” in showing leadership on COVID-19 vaccine conversation.
Jackson notes that the player leadership within the WNBPA saw the vaccine issue as connected to the league’s history of social activism, saying that they approached her with the message, “If Black Lives Matter is what we’re about, then in the public health space, this is really big for Black and Brown communities.” In August, the WNBPA partners with the Black Women’s Health Imperative and the National Council of Negro Women to launch a vaccination education campaign called “Take the Shot for the WIN”, which focused on promoting COVID vaccines among Black women, their families, and communities.

First COVID case at Tokyo Olympic Village
The first case of COVID-19 is detected at the Tokyo Olympic Village, a week before the Games are set to begin. The decision to continue with the Olympics despite the ongoing pandemic faces strong criticism from American media.
The Washington Post asserts that “Holding the Tokyo Olympics amid the COVID pandemic threat is about corporate revenue, not the athletes.” Slate declares that “The Tokyo Olympics Were Always Cursed.” Scientific American surveys public health experts who conclude that “COVID Risks at the Tokyo Olympics Aren’t Being Managed” and that “current prevention measures may not be enough to prevent an outbreak.” Science magazine runs a story with the headline, “Japanese scientists warn that Tokyo Olympics could help spread COVID-19” and details how local public health experts “struggle to be heard by government set on holding games.” Wired cautions that “The Olympics Could Be a Covid-19 ‘Super-Evolutionary Event’” since “the Games could provide a place for variants of the virus to spread and then return home with athletes.” Satoki Itani, professor at Kensai University, tells CNN how public opposition to the Games can be explained, “Their main concern is Covid-19, but there is also an increasing frustration and anger towards the attitudes and glaring disrespect to people’s lives here by the IOC, the Japanese government, and the organizing committee.”

NFL announces new COVID protocols with focus on vaccination
The NFL distributes a memo to its teams outlining the league’s COVID-operating principles. Much of the protocol focuses on vaccines with the memo stating, “We know that vaccines are safe and effective and are the best step anyone can take to be safe from the coronavirus.” The procedures for positive cases are very different for vaccinated and unvaccinated players.
Vaccinated players who test positive will be isolated but permitted to return to work after two negative tests at least 24 hours apart. Unvaccinated players will be subject to 2020 protocols and must isolate for 10 days and must be asymptomatic before rejoining their team. Unlike in 2020, no competitive accommodations will be made for teams unable to field a full roster due to COVID protocols; a failure to do so will be considered “conduct detrimental” to the league and will require the team to forfeit their schedule game. Allen Sills, NFL Chief Medical Officer, tells reporters that 80% of all players have received at least one dose of vaccine.
Although the league did not issue a mandatory vaccine mandate, some players explained how they felt coerced into vaccination. Seattle Seahawks cornerback D.J. Reed tweeted, “I didn’t want to get the vaccine. The NFL & NFLPA made getting the vaccine a competitive advantage. I just got my vaccine because I don’t want to hinder my team.” Arizona Cardinals star wide receiver De’Andre Hopkins posted a (soon deleted) tweet, saying, “Never thought I would say this, But being put in a position to hurt my team because I don’t want to take part in the vaccine is making me question my future in the @Nfl.” This backlash was in addition to previous criticisms made by Buffalo Bills wide receiver Cole Beasley whose defiant opposition to vaccination made him, along with Minnesota Vikings quarterback Kirk Cousins, a key figure in the NFL’s anti-vaccine movement.
Two of Beasley’s teammates, wide receivers Emmanuel Sanders and Stefon Diggs, post to social media publicizing their vaccinated status. Sanders posts a picture of his vaccine card to Instagram with the caption, “Availability. Accountability. Don’t have time to deal with no bs during the season.” Washington Football Team head coach Ron Rivera says that he is “beyond frustrated” with his team’s low vaccination rate even though he brought in medical experts to educate players. Rivera asserts, “I hope we can get to these guys, get them to understand really [that getting the vaccine is] not just for them, but it’s for the people around them. Rivera explains that he is immunocompromised after a cancer diagnosis the previous year and that his close interaction with potentially COVID-positive players “scares the hell of [him].”

US Swimmer Michael Andrew refuses vaccination before Olympics
Controversy swirls around American swimmer Michael Andrew’s public declaration that he was not vaccinated prior to the Tokyo Olympics. Andrew first justified his decision by citing concerns that vaccination might have induced side effects that would disrupt his training leading up to the Games. He later expanded his explanation during an interview with Fox News, stating, “Going to the Games not only unvaccinated but as an American, I’m representing my country in multiple ways and the freedoms we have to make a decision like that.”
American swimming gold medalist from 2016 Maya DiRado responded to Andrew’s comments in a Twitter thread, writing that she was “disappointed” in the reasoning behind his decision. She ended the thread by asking, “Are we protecting the vulnerable? Are we helping to stop the pandemic that is continuing to wrench loved ones from their families in both our home country and the country that’s hosting us? Michael does have the right to do anything – but not everything is beneficial.” Many of Andrew’s USA Swimming teammates defended his decision, including Patrick Callan, who tweeted “Michael is allowed to make his own decisions and I can guarantee you that none of us here are holding any decision like that against him.”

Tokyo Summer Games begin
The Tokyo Summer Games begin amid a COVID surge across Japan and only around 20% of the country’s residents vaccinated. The International Olympic Committee releases data saying that 127 people associated with the Games have tested positive for COVID-19 in the weeks leading up to the opening ceremonies. This number includes 71 residents of Japan (e.g., contractors and staff) and 56 non-residents (e.g., athletes, media members, officials, and other delegates). IOC president Thomas Bach asserts that the health and safety measures in place at the Games means that there is “zero risk” of COVID spreading from athletes to the Japanese public. Politico calls the Olympics “the ultimate Covid-19 experiment.”
These regulations include: testing protocols before traveling to Tokyo and upon arrival; quarantining upon arrival; daily testing and temperature checks; mask-wearing and social distancing; clapping instead of yelling to cheer on teammates; athletes are only permitted to leave to the Olympic Village or other IOC-approved accommodations to go to official venues. Vaccines are not required to compete but Bach estimates that around 85% or athletes will be vaccinated. Spectators will not be permitted at any Olympic venue or event.
Commentators highlight how these measures pose substantial challenges for athletes: restrictions on training during quarantine periods; the stress of daily testing; lack of social interactions with other athletes in quasi-bubble environments; and the psychological impacts of competing without the presence of fans and crowd noise.

Simone Biles withdraws from Olympic gymnastics competitions; prompts concerns over athlete mental health
American gymnast Simone Biles withdraws from the team competition and then the individual all-round competition at the Tokyo Olympics. Initial reports revealed that her exit from the competition was not a result of a physical injury but a “mental issue.” Biles explained to reporters that performance pressure made her unable to sleep leading up to the event and that her body was uncontrollably “shaking” before the competition. Biles continued, “I feel like it’s hard, but it’s harder being a female athlete because everybody prays for your downfall and wants you to mess up… at the end of the day, we’re not just athletes or entertainment. We’re human too and we have emotions and feelings and things that we’re working through behind the scenes that we don’t tell you guys about.”
Biles then posted a story to her Instagram account in which she said, “For anyone saying I quit. I didn’t quit. My mind & body are simply not in sync.” Biles then described the experience of having the “twisties,” the term gymnasts use when they lose their sense of bodily awareness and put themselves at serious risk of injury when twisting in the air.
Biles comments following her withdrawal from competition put mental health in the spotlight throughout the Olympics. Several other athletes began sharing their stories of emotional and psychological struggle leading up to the Games.
Some of these accounts recounted challenges specific to the pandemic. Many athletes experienced stress and anxiety related to the postponement of the Games and the subsequent uncertainty about when they would be rescheduled. These uncertainties disrupted training and qualifying schedules. Athletes also had to extend the duration of their intense pre-Olympic training regimens for another year, which put additional strain on their bodies. For many athletes, this fueled difficult questions about how much they could withstand the physical and psychological toll of this extra year of training.

MLB’s Blue Jays play first home game in Toronto since 2019
The Toronto Blue Jays play their first home game at Toronto’s Rogers Centre since September 29, 2019. US-Canada COVID-19 travel restrictions made it unfeasible for the team to play their home games in Toronto since they could not cross the border to play away games and opponents could not enter Canada for home games. The Blue Jays played their 2020 and 2021 home games in Buffalo and Florida until the Canadian government granted the team a “national interest” travel exemption on July 16.
The exemption requires pre- and post-arrival COVID-testing for all team members with unvaccinated individuals being subject to additional testing and a “modified quarantine” during which they will not be able to leave the team hotel except to attend games at the stadium. The team released a statement upon receiving the government exemption, saying, “First and foremost, the Blue Jays wish to thank Canadians for their unprecedented public health efforts and support for the team. Without you, Blue Jays baseball would not be coming home this summer.”

COVID concerns loom at Olympics’ halfway point
Halfway through the Olympic schedule, Tokyo reports a daily record of 4,058 COVID infections and the Japanese government extends its pandemic state of emergency measures. The rising cases spark more concerns about the severe strain being placed on hospitals and the country’s healthcare system. Canadian national newspaper The Globe and Mail asserts that “Japan’s Tokyo Olympics nightmare is coming true.”
Inside the Olympics bubble, organizers report a total of 259 cases since July 1 among athletes, staff, and officials with at least 3 individuals being admitted to hospital. International Olympic Committee spokesperson Mark Adams tells reporters, “As far as I’m aware, there is not a single case of infection spreading to Tokyo’s population from the athletes or Olympic movement.” This message is echoed by Japanese Prime Minister Yoshihide Suga, who states, “I don’t think there is any [COVID spread from the Olympics to the broader Tokyo population]. In order to avoid the spread of infection from foreigners to the Japanese, strict border measures are being taken.”

August 8

Tokyo Olympics conclude
The Olympics end with 458 total COVID cases associated with the Games (29 of which were athletes; 25 individuals were admitted to hospital). The Games are completed while Tokyo continues to experience record case numbers, surpassing 5000 daily cases for the first time on August 5.
Since the Olympics began on July 23, approximately 170,000 people in Japan contracted COVID and at least 178 people died. MSNBC runs a column detailing “COVID’s devastating toll on the Tokyo Olympics” whereas Aljazeera asks in a headline, “Did the Tokyo Olympics drive Japan’s COVID-19 surge?” The International Olympic Committee releases a statement calling Tokyo 2020 “a global health effort that’s given hope to the world.” The statement includes comment from Dr. Brian McCloskey, Chair of the Games’ independent panel of medical experts who says, “What Tokyo 2020 has just done in an historic way is show that the WHO advice is right. By following basic public health measures, and by layering a testing programme on top, we have shown that it is possible to keep a pandemic at bay.”
In December, the IOC announces that genomic sequencing data indicates that there was no COVID-19 spread between those inside the Olympic bubble and local Tokyo residents. Yet research also suggests that the Games may have indirectly contributed to rising infection rates by encouraging mass gathering to watch events and communicating a false sense of normalcy that made residents feel they could relax their adherence to pandemic measures.

Paralympics begin as COVID cases rise across Japan
The Paralympics begin with as state of emergency continues across Japan due to escalating COVID cases and a strained healthcare system. Like the Olympics a few weeks earlier, Paralympic events will be held with no spectators in attendance. 161 cases have been linked to the Paralympics so far, including six athletes. New Zealand’s Paralympic team announces that it will not be attending the opening ceremony, stating, “Our team will not be attending as we continue our commitment to our Covid-19 Operating Principles and Guidelines, aimed at keeping our team as safe as possible.”
Some commentators express concern that continuing the Games under these circumstances can endanger Paralympians with pre-existing conditions making them more susceptible to severe illness.
August 26
Paralympian admitted to hospital
Paralympic organizers confirm that a Paralympic athlete has been admitted hospital with COVID-19. The athlete, whose identity was not disclosed, is described as having “non-severe” symptoms. This development comes as Japanese health officials express concern about a shortage of available hospital beds as COVID cases continue to rise in Tokyo. Paralympic officials report 13 total cases inside the athlete’s village, including 5 athletes.

NFL’s Rodgers misleads on vaccination status
In comments that would soon prove controversial, Green Bay Packers star quarterback Aaron Rodgers tells reporters that he has been “immunized” against COVID-19. Rodgers goes on to say, “There’s guys on the team that haven’t been vaccinated. I think it’s a personal decision. I’m not going to judge those guys.” His statement does not attract much attention at the time and local media interpret his comments to mean that he had received an authorized COVID vaccine. On the same day, the NFL announces that 93% of its players have been vaccinated.

NBA will not have vaccine mandate for players
Reports indicate that the NBA will not require all players to be vaccinated for the 2021-22 season. Vaccination will be required for referees and staff working in close proximity to players. Such a protocol would align with rules instituted by MLB and the NFL.

NWSL’s Spirit found in violation of COVID protocols
The Washington Spirit of the NWSL forfeit their second straight match due to their breach of league COVID protocols. The match was initially postponed when the Spirit had four positive COVID cases within the team but their violation of league protocols meant they would no longer be accommodated with a rescheduled match. The team was also fined $25,000.
The Spirit released a statement saying, “We, the members of the Washington Spirit organization, sincerely apologize and take full responsibility for breaking protocols that forced our previous two matches to be cancelled,” the Spirit said in a statement. “We understand our actions have serious consequences and we have let our fans down. Moving forward, we are committed to being better and adhering to all protocols.”
September 28
NBA sets COVID rules for upcoming season
The NBA releases its COVID protocols for the 2021-22 regular season. The protocols will implement stricter rules for unvaccinated players including more frequent testing than vaccinated players, masking requirements, restrictions on eating meals with teammates and leaving team hotels on road trips, and prohibition from “high risk settings” such as restaurants, bars, entertainment venues and other large indoor gatherings. An NBA spokesman states that the league had proposed a full vaccine requirement for all players but their request had been rejected by the NBA Players Association.
Many NBA stars such as Anthony Davis, Damian Lillard, and Giannis Antetokounmpo confirm that they have been vaccinated. LeBron James also announces that he has been vaccinated after his initial skepticism about the safety and effectiveness of the vaccines. He says that getting vaccinated “was best suited for not only me but my family and my friends.”
Other high profile players including Bradley Beal and Andrew Wiggins indicate that they have not been vaccinated. Brooklyn Nets star Kyrie Irving does not disclose his vaccination status and “asks for privacy” around this issue.

NBA teams announce rules for fan attendance at 2021-22 games
With the NBA season starting in less than three weeks, 15 of the league’s 30 teams release COVID policies for fans attending future games. Four teams (Brooklyn, Golden State, New York, and Toronto) will require fans to provide proof of vaccination when entering their home arenas with no exceptions. Eleven other teams will require fans be vaccinated or present results of a recent negative COVID test. These rules are additional to a league-wide policy stipulating that all fans sitting within 15 of the court or player benches must provide proof of vaccination or results of a negative test.
Each individual arena will also have its own mask policy aligned with local or team rules. Many arenas, such as Los Angeles’ Staples Center and Charlotte’s Spectrum Center, require fans to wear masks unless they are eating or drinking in their assigned seats. In other venues, such as Atlanta’s State Farm Arena or Detroit’s Little Caesar’s Arena, masks are only recommended and not required. As the season progresses, reports from some NBA cities indicate minimal compliance with mask requirements.
The NHL has a similar range of vaccine/mask policies at team arenas, some of which are shared with NBA teams.

ESPN suspends broadcaster Sage Steele for COVID comments
Steele is suspended after she criticized the COVID vaccination policy of the network’s parent corporation Walt Disney Company, calling the mandate “sick” and “scary.” She went on to explain that she did not want to get vaccinated but felt forced to comply with company policy. The network says in a statement, “At ESPN, we embrace different points of view — dialogue and discussion make this place great. That said, we expect that those points of view be expressed respectfully, in a manner consistent with our values, and in line with our internal policies.”
Steele responds to ESPN’s decision in a statement, saying “I know my recent comments created controversy for the company, and I apologize. We are in the midst of an extremely challenging time that impacts all of us, and it’s more critical than ever that we communicate constructively and thoughtfully.”

NBA reports high rates of vaccination; unvaccinated players must comply with local rules
NBAPA president Michele Roberts states that 96% of NBA players have been vaccinated. NBA officials also warn that forthcoming city-imposed vaccination mandates will impact unvaccinated players’ eligibility to play games and practice at team facilities.
Mandates have been announced (or are expected) in New York City (New York Knicks, Brooklyn Nets), San Francisco (Golden State Warriors) and Los Angeles (Los Angeles Lakers and Clippers). The mandates dictate that employees of businesses located in these cities must be vaccinated to work in-person. Unvaccinated players on visiting teams are exempt from these rules since their employers are located in places outside the city’s jurisdiction. Unvaccinated players visiting Canada to play the Toronto Raptors are subject to a modified quarantine system (similar to that implemented for MLB’s Toronto Blue Jays) whereby these players are prohibited to from leaving their team hotel except to attend the scheduled game.
The NBA asserts that unvaccinated players ineligible to play home games due to local mandates will lose their salary for those games.
October 12
NBA’s Irving unable to participate in team activities without vaccine
The Brooklyn Nets announce that star point guard Kyrie Irving will not be permitted to play or practice with the team until he is vaccinated. Irving is unable to play home games in Brooklyn due to New York City vaccine mandates but is still eligible to play in Nets away games. The team writes in a statement, “Kyrie has made a personal choice, and we respect his individual right to choose. Currently the choice restricts his ability to be a full-time member of the team, and we will not permit any member of the team to participate with part-time availability.”
Irving, who will lose $380,000 for each home game missed, responds by saying he accepts the “reality that in order to be in New York City, in order to be on a team, I have to be vaccinated. I chose to be unvaccinated, and that was my choice.” He also clarifies that his decision is “not about being anti-vax” but that he believes his choice is “what was going to be best for me and my family.”
NBA Commissioner Adam Silver issues a reminder of the difference between a player’s personal choice on an issue and their requirements as a worker, saying “having an opinion about whether to get vaccinated is different than your right to play NBA basketball. We’re seeing that, for example, in the New York market right now, when there’s a conflict with a player’s point of view and the local law, and the local law is going to trump that player’s point of view.”

NBA’s Wiggins reluctantly gets vaccinated
Golden State Warriors forward Andrew Wiggins, who was denied a “religious exemption” to vaccinated from the league, announces that he has been vaccinated. He explains that he felt “forced” to do so and that he believed “the only options were to get vaccinated or not play in the NBA.” Wiggins tries to justify his hesitation by saying, “I know a lot of people get reactions or injuries from getting the vaccination, so I don’t know what it’s going to do to me in 10 years.”
Journalists and public health officials have pushed back on the misinformation communicated by these and other unvaccinated NBA players. Dr. Anthony Fauci warned in an interview that the players were sharing theories about vaccinations harms that were “just not factual.” Fauci also clarifies that “although there are individual choices that people can make, when you’re dealing with a deadly pandemic, you’ve got to also understand your responsibility to the society within which you live.” Other commentators highlight the unfortunate acceptance of vaccine misinformation among NBA players and lament that few players are publicly counteracting this trend by promoting vaccines.

NHL suspends Kane for faking vaccine certificate
The NHL suspends Evander Kane, forward for the San Jose Sharks, 21 games for violating the league’s COVID protocols. Kane was found to have submitted a counterfeit COVID-19 vaccination card prior to the start of the season, which would have exempted him from the league’s stricter protocols for unvaccinated players. Kane issued a statement reading, “I would like to apologize to my teammates, the San Jose Sharks organization, and all Sharks fans for violating the NHL COVID protocols. I made a mistake, one I sincerely regret and take responsibility for.”

NBA’s Goodwin makes unsubstantiated claim about blood clots and COVID vaccine
In comments widely circulated on Instagram, free agent NBA guard Brandon Goodwin claimed that his COVID vaccination resulted in the development of blood clots that made him miss part of the 2020-21 season with the Atlanta Hawks. Goodwin said that the vaccine was “a thousand percent” responsible for the onset of these blood clots. His claim, presented without supporting evidence, came after the Center for Disease Control (CDC) expressed concerns in April about blood clots as a rare side effect of the Johnson & Johnson COVID vaccine. The CDC and Federal Drug Administration then recommended a pause on the use of the J&J vaccine.
Experts were quick to refute Goodwin’s unsubstantiated claims, however, stressing the extreme rarity of the J&J side effect and explaining that blood clots were more likely to be a result of recent COVID infection. Importantly, elite athletes also tend to be more susceptible to blood clots than the general population. Goodwin seemed to rescind his claim, tweeting, “I got sick. Maybe it was the vaccine maybe it was covid [I don’t know] I’m not a expert.”

Beijing 2022 Olympics COVID rules released
The International Olympic Committee and International Paralympic Committee publish their Beijing 2022 Playbooks, which include COVID-19 guidelines. The Playbook outlines how the Games will be hosted across three “Olympic Zones” in Beijing, Zhangjiakou and Yanqing that will comprise a closed loop of facilities connected by dedicated transportation routes. All competition and training venues, as well as the Athlete Village, are contained within the loop and participants are forbidden from leaving the loop system to “ensure there is no contact with the general public.” As was previously announced, unvaccinated athletes will have to undergo a 21-day quarantine before entering the closed loop system.
Athletes will be subjected to daily testing and will be asked to wear masks whenever they are not competing, training, eating, drinking or sleeping. Anyone who tests positive during the games will be taken by “dedicated transport either to an isolation facility or to a hospital to isolate and/or receive medical treatment”. Athletes are also instructed to avoid physical interactions (including hugging and high-fives) are kept to a minimum.
An updated final version of the Playbooks is published in December.

Research investigates COVID spread during college football games
A study by researchers from Texas A&M, The University of Florida, and Louisiana State University suggests that college football games did not facilitate high levels of COVID spread among participating players. The researchers conclude that this low infection rate was promoted by Conference-wide COVID rules including regular testing and isolation protocols, as well as the relative safety of outdoor activities during the pandemic. The results mirror those from studies of other outdoor sports such as rugby that also found minimal transmission during matches. Commentators argue that these findings have significant implications beyond sports and should encourage public health authorities to promote the safety of outdoor activities and relax remaining masking requirements in outdoor spaces.
Importantly, the college football season took place in between America’s summer COVID wave spurred by the Delta variant and the beginning of the country’s immense Omicron wave that began in December (and had major impacts on end of season playoffs and Bowl games).
This study comes only a few weeks after University of Florida issued a press release announcing that “So far, COVID-19 spikes from college football games haven’t materialized.” Based on the work of UF epidemiologist Cindy Prins, the release asserts that there have been few COVID outbreaks associated with fans attending college football games at packed stadiums across the country. Citing the outdoor locations of most college football games and fans limited exposure to other people beyond those seated immediately around them, Prins suggests that football games are “not the super spreader events that people have worried they’re going to be.” Indeed, many commentators expressed concern about mass gatherings at NFL and college football in articles with headlines such as “Will College Football Games Become Covid-19 Coronavirus Super Spreader Events?” and “Crowded stadiums, pandemic create combustible mix this fall.”
Importantly, these fall football seasons took place in between America’s summer COVID wave spurred by the Delta variant and the beginning of the country’s immense Omicron wave that began in December (and had major impact on the end of these football seasons).

NFL’s Rodgers tests positive for COVID-19; confirms he is unvaccinated.
Green Bay Packers quarterback Aaron Rodgers is ruled out of the team’s Week 9 game after testing positive for COVID-19. That Rodgers was immediately deemed ineligible for the game raises questions about his vaccinated status since NFL protocol allows vaccinated players to return to play if they receive two negative tests at least 24 hours apart (unvaccinated players are required to isolate for a minimum 10 day period). Reporters soon confirm that Rodgers is indeed not vaccinated, seemingly contradicting his earlier statement that he had been “immunized” against COVID-19.
The NFL subsequently fines Rodgers and the Packers ($14,650 and $300,000 respectively) for violating the league’s COVID rules.
Rodgers soon adds to the controversy during an appearance on the radio program, The Pat McAfee Show. Rodgers first reveals that the Packers were aware of his unvaccinated status. He claims that he is allergic to ingredients in the COVID-19 mRNA vaccines and was concerned about the vaccine’s impact on male fertility (a concern not supported by scientific evidence). He says that he underwent a homeopathic “immunization” treatment to “stimulate my immune system to create a defense against COVID.” He also criticizes NFL COVID policies and condemns the league and media for “shaming” unvaccinated players. He also cites “cancel culture” and the “woke mob” as primary drivers of a “witch hunt” directed at unvaccinated individuals. Rodgers then discloses that he had taken two unapproved (and ineffective) medications – hydroxychloroquine and ivermectin – to treat his COVID infection after consulting with controversial podcast host Joe Rogan.
Rodgers’ position is widely criticized by medical experts as inaccurate and harmful. The New York Times calls Aaron Rodgers “a new source of vaccine misinformation.” Doctor and professor Eric Cadesky writes that Rodgers has “amplified dangerous and disproven myths about the COVID-19 vaccine” that have led to serious consequences including “physical violence against doctors, death threats against public health officials and protesters blocking cancer patients from entering hospitals.” Rodgers then admits that he “made some comments that people might have felt were misleading” and asserts that he takes “full responsibility for those comments.”

Australian Open will have vaccine requirement
Organizers from the Australian Open confirm that all players must be vaccinated to participate in the tennis tournament scheduled to begin on January 17, 2022 in Melbourne. Tournament director Craig Tiley stated, “There’s a lot of speculation about vaccination, and just to be really clear, when the [state] premier announced that everyone on site…will need to be vaccinated…we made that clear to the playing group.”
This announcement is especially significant for the status of #1 ranked men’s player Novak Djokovic, who has refused to disclose his vaccination status throughout the pandemic and has previously spoken out against tournaments requiring all competitors to be vaccinated. Tiley commented on Djokovic’s status, saying, “He has said that he views this as a private matter for him. We would love to see Novak here. He knows that he’ll have to be vaccinated to play here.”
Australia has had some of the most stringent travel restrictions throughout the pandemic, which largely mitigated COVID-spread inside its borders but also left some citizens living abroad unable to visit. The country only eased travel restrictions for fully-vaccinated citizens in October. On November 22, government officials announce that some non-citizens (such as skilled workers and students) would be allowed to travel to Australia if they are fully vaccinated. Australia would not permit the entry of tourists and other international visitors until late-February 2022.

Philadelphia Union to miss 11 players for MLS Conference Final
Major League Soccer’s Philadelphia Union will be without 11 players for the team’s Eastern Conference final game against New York City FC due to league COVID protocols requiring players to isolate if they come in contact with a suspected case. Coach Jim Curtin confirms that all Union players had been vaccinated.
The team is able to sign three replacement players for the game on “hardship” contracts, yet the shorthanded Union loses to NYCFC 2-1.

Unvaccinated Irving to return to Nets for road games
The NBA’s Brooklyn Nets announce that star guard Kyrie Irving will rejoin the team on a part-time basis for the remainder of the season. Irving, who is unvaccinated, will only play in the team’s road games since New York City mandates still prohibit unvaccinated employees of city businesses from working in person. The Nets’ decision counteracts their earlier refusal to allow Irving to be a “part-time participant” in team activities. Irving plays in his first 2021-22 regular season game with the Nets on January 5.

Pro Leagues impacted by onset of Omicron wave
With the Omicron variant surging across North America, professional leagues are impacted with high numbers of COVID cases and game cancellations. The NFL recorded over 100 positive tests in the previous week, which required the league to postpone three games. The NBA had to postpone 5 games with multiple teams experiencing large-scale outbreaks. The Brooklyn Nets and Philadelphia 76ers are currently unable to field the minimum eight player roster with so many players in COVID protocols.
The NHL had to postpone 44 games over the past two weeks with over 15% of the league’s players in COVID protocol. The NHL also announces that the league will be pausing its season from December 22 to 26 to avoid additional postponements by allowing time for currently infected players to recover and rejoin their teams. The NHL and NHLPA also agree to withhold players from participating in the 2022 Beijing Winter Olympics due to COVID concerns.
These developments demonstrate how the highly contagious Omicron variant can circumvent “the strictest protocols” that had been relatively effective at mitigating the impact of the Delta variant on professional sports leagues.

NCAA Bowl games canceled or modified due to high COVID cases
The Hawaii Bowl, the Military Bowl, the Fenway Bowl, the Arizona Bowl, and the Holiday Bowl are canceled due to rising COVID case counts on participating teams. Other bowl games have teams withdraw on account of COVID outbreaks, but are replaced with alternate teams so the games can still take place.
Remainder of World Junior Men’s Hockey Championships canceled
The International Ice Hockey Federation (IIHF) announces that the remainder of the 2022 World Junior Hockey Championship in Alberta, Canada will be canceled after four days of play due to positive COVID cases among tournament participants. COVID infections had already necessitated the forfeiture of three tournament games and the IIHF affirms that “the sportive integrity of the event has been compromised.” IIHF President Luc Tardif says in a statement, “We owed it to the participating teams to do our best to create the conditions necessary for this event to work. Unfortunately, this was not enough. We now have to take some time and focus on getting all players and team staff back home safely.”
