Steelers Injury Report: Keenan Lewis, Mike Adams, Troy Polamalu

While Pittsburgh Steelers offensive lineman Mike Adams was able to practice at a limited capacity on Thursday, safety Troy Polamalu and cornerback Keenan Lewis were sidelined due to injury. Lewis sustained a hip flexor during a Week 14 matchup against the San Diego Chargers and aggravated the injury last weekend against the Dallas Cowboys. He apparently once again aggravated it during Wednesday’s practice and didn’t suit up yesterday as a result. Pittsburgh finds itself extremely thin at corner as they have already ruled veteran Ike Taylor out for this weekend’s matchup against the Cincinnati Bengals. Polamalu was given the day off due to a non-injury-related issue, most likely so the team can better ensure his health for this weekend’s pivotal contest against the Bengals. While Adam was able to return to practice at a limited capacity, he is not expected to play this weekend.
