NBA players unvaccinated against COVID-19 risk losing salary if they are not able to play in games due to non-compliance with local health protocols.

NBA spokesperson Mike Bass confirmed on Wednesday that players will not be paid should they miss games for that reason, as vaccination status continues to be a thorny issue for some of the league's high-profile stars.

Major cities such as New York and San Francisco have laws that restrict unvaccinated persons from entering sports arenas, restaurants and other public spaces.

That means players such as the Brooklyn Nets' Kyrie Irving and Andrew Wiggins of the Golden State Warriors face being unable to play home games and losing significant portions of their salary.

Players travelling to those areas would also miss out on pay for failing to comply with local mandates.

Both Irving and Wiggins have salaries over $30million for the 2021-22 season.

"Any player who elects not to comply with local vaccination mandates will not be paid for games that he misses," Bass said.

Wiggins this week saw his request for a vaccine exemption on religious grounds rejected by the NBA, having previously said he would not get the vaccine unless he was forced into doing so.
