Michael Pittman, wide receiver for the Indianapolis Colts, suffered a concussion during Saturday's game against the Steelers and will not return. He took a big hit from Steelers safety Damontae Kazee in the second quarter, resulting in Kazee's ejection from the game. Pittman will now go through the concussion protocol and will need to be cleared before returning to action. The Colts' next game is on Sunday, December 24th against Atlanta.
