Ball was placed in the NBA's health and safety protocols Sunday, Adrian Wojnarowski of ESPN reports.
Ball was one of the few members of the Bulls who had yet to enter the league's COVID-19 protocols coming into Sunday but could only hide for so long. He becomes the third player for Chicago to be placed in protocols Sunday, joining Alonzo McKinnie and Tony Bradley. Coby White should slide into the starting five while Ball is out. Ball must have two consecutive negative PCR tests within a 24-hour span if he's to return prior to Jan. 7.
