Remaining unvaccinated was a US$100 million (NZ$177m) decision, according to Brooklyn Nets guard Kyrie Irving.
The seven-time NBA All-Star says his choice to forgo COVID-19 vaccinations forced him to decline a hefty contract extension with the Nets.
"I gave up four years, 100-and-something million deciding to be unvaccinated, and that was the decision," Irving said. "[Get this] contract, get vaccinated or be unvaccinated, and there's a level of uncertainty of your future, whether you're going to be in this league, whether you're going to be on this team, so I had to deal with that real-life circumstance of losing my job for this decision."
Irving couldn't play home games for the Nets last season, until New York City's vaccination mandate was lifted in March. He was also unavailable for some road games, due to local vaccine requirements.
He will play for Brooklyn in the 2022/23 season on a US$36.5 million (NZ$64.8m) player option, before potentially becoming a free agent next summer.
Irving admits he expected to sign a long-term contract with the Nets in the summer of 2021.
"We were supposed to have all that figured out before training camp last year," Irving said. "And it just didn't happen, because of the status of me being vaccinated, unvaccinated.
"I understood their point and I had to live with it. It was a tough pill to swallow, honestly.
"I felt like I was forced with an ultimatum of whether or not I had a contract or not, whether or not I can be on the team [based on] whether or not I was vaccinated. I was definitely put in that position where I had to make that decision."
Nets general manager Sean Marks disputes Irving's characterisation of the talks.
"There's no ultimatum being given here," Marks said. "Again, it goes back to you want people who are reliable, people who are here and accountable... all of us - staff, players, coaches, you name it.
"It's not giving somebody an ultimatum to get a vaccine. That's a completely personal choice.
"Two summers ago, when we were talking about contract negotiations, that was pre-citywide mandates that went in. Once the vaccine mandates came in, you knew how that'd affect playing home games.
"That's when contract talks stalled. It didn't get to, 'Here's the deal, now take it back' - that never happened."
Irving, 30, wound up playing 29 games last season, averaging 27.4 points, 5.8 assists and 4.4 rebounds. In his 11-year career with Cleveland Cavaliers (2011-17), Boston Celtics (2017-19) and Brooklyn (2019 to present), he has career norms of 23.1 points, 5.7 assists and 3.8 rebounds in 611 games, all starts.
Irving, who won an NBA championship with the 2015/16 Cleveland Cavaliers, acknowledged that his vaccine choice negatively affected his public image.
"I didn't appreciate how me being unvaccinated, all of a sudden, came to be a stigma within my career that I don't want to play," he said.
