Gibson (ribs) didn't end up playing Saturday against the Pistons.

Analysis:

Gibson was supposed to be available off of the bench after missing the team's previous game, but ultimately wasn't called upon by coach Fred Hoiberg. The veteran is is one of the toughest players on the Bulls, so he must be really hurting if he can't make his way onto the floor while the Bulls are fighting for their playoff lives. It's unclear if he will be able to play Sunday against the Bucks, but it would be hard to expect him to play significant minutes even if he does suit up.
