All NBA personnel (players, coaches, staff) will be required to undergo daily COVID-19 testing to ensure everybody is healthy and safe to proceed with the season. Players will not be allowed to shower at the facilities where games will be played; they will be required to instead shower at their hotels.
When not playing, active players will be spaced out on the bench to ensure social distancing is being followed, while inactive players will be required to sit in the stands. Guests of the players are not allowed to be in attendance until after the first round of the Playoffs (limited to three guests per player).
The plan right now is that no fans will be allowed to attend any games during the entirety of the 2019-20 season in Orlando, Florida. With the state of Texas already publicly allowing 50% capacity at stadiums that fit close to 100,000 people, this could be subject to change over the coming months. Considering the NFL season is planning on starting in September with no current limitations on fan attendance, the NBA might be allowing fans in attendance sooner than people currently believe.
Another key aspect of this is if a player tests positive for Corona, he will be required to quarantine for at least seven days until he tests negative multiple times. The rest of the team will be tested (as they will be on a daily basis either way) and will be able to proceed as usual without that player who tested positive.
The only potential issue that hasn’t yet been addressed is if numerous players on the same team test positive. Will the team have to forfeit those games? Does the NBA suspend those games until they’re cleared to play? Hopefully, answers to those questions will never need to become relevant.
