Unvaccinated NBA players and staff members will be required to test weekly for COVID-19, said a league memo on Tuesday.

The new policy had been developed for several weeks and it was agreed upon by the National Basketball Players Association.

"It looks like we’ll be on our normal track in terms of when the season starts, in terms of our protocols around the game, particularly around the health and safety of our players," NBA Commissioner Adam Silver said at the league’s Board of Governors meeting in July. "I have learned over the last two and a half years not to make any predictions when it comes to COVID, but only to say we’ll be prepared for anything that comes our way."
