Pittsburgh Steelers head coach Mike Tomlin has already ruled safety Troy Polamalu (calf), offensive tackle Marcus Gilbert (ankle) and linebacker Chris Carter (hamstring) out this week against the Cincinnati Bengals on Sunday Night Football. According to Steelers.com:

Gilbert left last Thursday’s game against the Tennessee Titans with an ankle injury, and after seeing a specialist in Charlotte, North Carolina on Monday it was determined he won’t have to have surgery.

"He has a tendon injury in his ankle," said Coach Mike Tomlin. "It does not require surgery. He is week to week. He will be out this week. But it was a positive meeting in that the injury does not require surgery."

Former Bengals linebacker Brandon Johnson is already being "characterized" by Tomlin as "questionable".
