The Bulls might move forward Tyrus Thomas into the starting lineup as rookie Taj Gibson battles a foot injury.
Chicago disclosed on Tuesday that Gibson has been battling plantar fasciitis in his left foot for much of this season.
"He's feeling better, but the plantar fasciitis has bothered him and he needs some treatment," coach Vinny Del Negro said of Gibson. "He just really irritated it the other night in a game."
Thomas would reclaim the starting power forward spot if Gibson can't go on Thursday night against the Celtics.
He lost the spot when he injured his forearm and Gibson's strong play kept Thomas from regaining it upon his return.
"Tyrus played well (Monday against the Pistons) and had a good practice (Tuesday) too," Del Negro said. "He was under control. I loved his activity."
