Players on the Golden State Warriors, Brooklyn Nets, and New York Knicks better get their COVID-19 jabs.

The NBA and National Basketball Players Association are ramping up efforts to encourage its players to receive the COVID-19 vaccine. According to The Athletic's Shams Charania, in markets with local requirements mandating proof of vaccination for indoor events — such as New York and San Francisco — NBA players who remain unvaccinated will not be allowed in arenas unless approved for “medical” or “religious” exemptions.

It's unclear what precisely justifies a “religious” exemption.

As Charania noted in his follow-up tweet, the NBA will abide by the requirements of local governments, which vary from city to city. However, if the season started today, any unvaccinated players on the Warriors, Knicks, and Nets would not be allowed to play in home games. The league's mandate does not apply to players visiting San Francisco and New York.

As of July, NBPA director Michele Roberts revealed that over 90% of active players have gotten the jab.

The NBA is working to get as many league personnel vaccinated ahead of the 2021-22 season. A few days ago, The Athletic reported that any person who will be interacting with players, along with team and arena employees, will have to be vaccinated. This includes coaches, front-office staff, officials, medical personnel, PR and social media teams, arena security, etc.

Barclays Center has announced that any employees and fans over the age of 12 will have to show proof of vaccination to enter the premises. The Sacramento Kings are mandating that all employees get vaxxed by Nov. 1.

The Warriors announced that any indoor event with at least 1,000 attendees will require fans 12 and older to show proof of vaccination by mid-September.
