Weeden was injured during the fourth quarter of Sunday's game. Weeden's concussion may have come when he banged his head against the leg of teammate Joe Thomas while attempting to throw a pass. Weeden was replaced for the final two series of the game by backup quarterback Colt McCoy. McCoy suffered a concussion in his previous game against the Steelers in Week 14 of 2011.
McCoy did not attempt a pass in the game as the Browns used run plays to bleed the clock. Weeden's day finished 17-of-26 for 158 yards, one touchdown and one interception, which was returned 53 yards for a touchdown by Steelers linebacker Lawrence Timmons. Weeden was also sacked four times during the game. After the game, Browns head coach Pat Shurmur confirmed that Weeden was being treated for a concussion.
