Jim O'Connor-US PRESSWIRE
Isaac Redman will not return to Sunday night's game after suffering a concussion.
Redman had rushed for five yards on one carry on the night before he was removed from the game for evaluations. After extensive tests, Redman was declared to have a concussion and will not return on Sunday night because of the head injury.
Redman is among a bevy of Steelers to record some rushing yards on the night, but quarterback Byron Leftwich is surprisingly leading the team's leading rusher at half, with one rush for 31 yards that resulted in the Steelers' lone touchdown of the night.
The Steelers trail the Ravens, 10-7, at half in a key AFC North showdown between the two teams. The Ravens scored their touchdown on a Jacoby Jones punt return for a touchdown.
