CINCINNATI -- Steelers linebacker James Harrison is inactive for a game against the Bengals because of a knee injury.
Harrison played for the Bengals last season before returning home to the Steelers. He had been listed as doubtful. Pittsburgh also is missing defensive end Brett Keisel, who tore his triceps during a loss to New Orleans last Sunday and is out for the season.
Ben Roethlisberger is starting. He hit his throwing hand on a helmet against New Orleans and didn't practice on Wednesday. He was back the following day.
Defensive tackle Domata Peko is active for the Bengals despite an elbow injury that limited him during a win at Tampa Bay last week. Clint Boling starts at right tackle for the first time.
