The NBA and NBPA have set their guidelines on player guests starting after the first round of the playoffs.
Each player will be allowed to bring up to four guests, but that number can be exceeded to include children. Players will be allowed to bring family members and "established longstanding personal friends."
"Any individual the player has not previously met in person or with whom the player has had limited in-person interactions. (For example)... known by the player only through social media or an intermediary" will not be allowed on campus.
Guests can travel on team chargers following testing and they also will be allowed to attend games.
