The Chicago Bulls, who played the Hornets on Monday, saw Javonte Green test positive for COVID-19 on Friday, following Coby White earlier this week.
Charlotte had four players enter health and safety protocols on Saturday.
Bulls coach Billy Donovan said before his team faced the Nets in Brooklyn Saturday night that Green had driven back to Chicago on Friday, and was feeling all right. He added that Chicago expects to continue daily testing in the wake of multiple positive tests, and that he anticipates the league continuing to tighten its protocols as time goes by.
