It was a tough night for the Steelers in many ways against Baltimore.
Four players left the game with injuries, and two of them are done for the season.
Rookie halfback Rashard Mendenhall and right guard Kendall Simmons will be placed on injured reserve today. Mendenhall made his first start and he left in the third quarter with a fractured shoulder. Simmons has a torn Achilles tendon.
Backup linebacker Andre Frazier was carried off the field on a stretcher when he was injured on the opening kickoff, but he was judged to be OK and was in the locker room after the game after the Steelers announced he had a spine injury.
Running back Carey Davis left the game early in the fourth quarter with a sprained ankle.
Darnell Stapleton replaced Simmons, playing with the first-team offense for the first time in his two years.
The injuries to the running backs left the Steelers with just one healthy back, Mewelde Moore. They went into the game with just three. Gary Russell was on the roster until he was released the day before they played Philadelphia, and re-signed to the practice squad.
They likely will add Russell to their 53-man roster this week and may have to sign another running back because starter Willie Parker is expected to miss next Sunday's game in Jacksonville with a sprained knee.
