The Facts: After finally returning from a four-game absence to play in Monday night's victory against the Washington Redskins, Parker has a new injury -- an ailing shoulder -- and will not play against the Indianapolis Colts.

Diehards Line:Parker injured his shoulder sometime in the third quarter against the Redskins -- "I'm not sure how," he told the Post-Gazette -- but still finished the game. His shoulder did not begin aching until the next day, and he has not practiced this week. He is expected to miss only one game and will be replaced by Mewelde Moore, who averaged 101 yards rushing and scored four touchdowns in three previous starts.
