The NBA has postponed the Bulls-Pistons game on Tuesday and Bulls-Raptors on Thursday amid Chicago's coronavirus-related roster crisis, the league announced.
The Bulls had 10 players in the league's health and safety protocols as of Monday morning and were in jeopardy of not having enough healthy players to field a team Tuesday.
Forward Alize Johnson tested positive for COVID-19, a source told ESPN's Adrian Wojnarowski, and entered the protocols Monday.
The minimum requirement of players for a game is eight.
Johnson joins a lengthy list of Bulls in the league's health and safety protocols that includes Zach LaVine, DeMar DeRozan, Troy Brown Jr.
