Gibson has been playing through a left shoulder injury, the Chicago Tribune reports.

Analysis:

We've known about this injury for a while, but Gibson reaffirmed Thursday that he's still bothered by the shoulder. "It's tough," Gibson said. "But you still have to go out there and do your best." Gibson received a cortisone shot in the shoulder last week, and he continues to receive treatment before and after games. The forward has struggled offensively thus far in the Bulls' first-round series, but he hauled in 10 rebounds in Game 1 and pulled down 10 in Thursday's Game 3.
