Deng is dealing with a left thigh bruise, but it hasn't kept him out of game action. He scored 27 points in the Bulls' 114-81 victory over the Atlanta Hawks on Tuesday.
Gibson is nursing an injured right big toe, and Watson has plantar fasciitis in his right foot. Neither player has missed a game because of the injuries.
The Bulls have won 10 of their last 11 games and have a one-game lead on the Boston Celtics for the No. 1 seed in the Eastern Conference.
