Collins (undisclosed) exited to the locker room in the fourth quarter of Wednesday's 135-105 loss to the Knicks, finishing with three points (1-4 FG, 0-2 3Pt, 1-1 FT), three assists, one rebound and one steal across 14 minutes.
Collins headed back to the locker room with a trainer and did not return. He can be considered questionable for Sunday's game against the Sixers until the Bulls offer an update on his status. If the big man is forced to miss time, Leonard Miller could see increased burn.
