Collins (undisclosed) exited to the locker room in the fourth quarter of Wednesday's game against the Knicks, K.C. Johnson of Chicago Sports Network reports.
It's unclear why Collins exited to the locker room with a trainer, though it's unlikely he'll return in the final minutes of this blowout. If he's forced to miss time, Leonard Miller would likely see increased burn, especially if Jalen Smith (hand) joins Collins on the inactive list.
