On December 17, Beijing time, the 2021-22 NBA regular season was in full swing. According to Shams, the NBA has introduced new epidemic prevention regulations for Christmas.

The NBA league and the players' union reportedly agreed on an agreement on epidemic prevention over the Christmas period, which includes daily nucleic acid testing while increasing the use of masks. Daily nucleic acid testing is required from 26 December to 8 January. It should be noted that players who have already been injected with a booster needle and have recently recovered are not tested.
Since entering December, the COVID-19 pandemic has once again hit the NBA league. According to statistics, more than 50 players have triggered health and safety agreements this month, including the Bucks' alphabet brother, the Nets' Harden, the Lakers' Westbrook and many other superstars. 76ers coach Rivers has bluntly said that he is worried that the NBA will once again fall into a shutdown.
Also, earlier today, former Timberwolves vice president Robby Sikka said, "The alliance has started to take a number of steps to deal with this recent wave. Players without injections of booster needles must be tested on every matchday starting on Friday, and the test on training days is a consideration. Meanwhile, the league is considering whether to allow players who test positive for COVID-19 but asymptomatic to continue playing and avoid entering the agreement, but are not yet ready to implement it. ”
