Polamalu hurt the strained calf again in the first quarter, leaving the game without returning. Although James Harrison's return helped the Steelers' defense, the team lost another linebacker, as Lamar Woodley strained his right hamstring early in the game as well. According to Mike Tomlin after the game, it's unclear whether either player will be able to go after a short turnaround for the team's Thursday night game at Tennessee.
Elsewhere in the AFC North, the Cincinnati Bengals lost running back Bernard Scott as he left the game against the Miami Dolphins with a left knee injury. Scott, who had just recovered from an earlier ankle injury, had -5 yards on the season entering the game, but busted out a 29-yarder in the first quarter. Despite leaving the game early, he led the Bengals in rushing with 40 yards. The extent of his injury is unknown.
The Cleveland Browns suffered some losses to their defense, including D'Qwell Jackson. The linebacker left the game with a concussion and did not return. The league's concussion policy will probably mandate how soon Jackson can return to action. The team also saw defensive tackle Ahtyba Rubin and cornerback Dimitri Patterson leave with ankle and leg injuries.
The Baltimore Ravens suffered no injuries in their 9-6 win over Kansas City. Terrell Suggs remained out with an Achilles tendon injury and will remain out likely through the team's Week 8 bye week, if not longer.
