The Bulls-Pistons game was postponed by the NBA due to Chicago's coronaviruses-related roster crisis.
The Bulls had 10 players in the league's health and safety protocols as of Monday morning and were in danger of not having enough healthy players to field a team Tuesday.
A source told Adrian Wojnarowski that forward Alize Johnson tested positive for COVID-19 and entered the protocols Monday.
The minimum number of players for a game is eight.
The Bulls have a long list of players in the league's health and safety protocols.
Once players enter the league's protocols, they must be on a 10-day quachicle until they return two negative tests within 24 hours.
The Bulls have added at least one new player to their health and safety protocols for three days in a row. The team did not practice on Monday.
