AFC North injury impact

Here are the main injuries around the division and what they mean:

BENGALS: Cincinnati could be starting two backups on the right side of the offensive line. Mike McGlynn is taking over at RG for Bobbie Williams, who has been placed on injured reserve. RT Andre Smith (ankle, questionable) didn't practice Thursday and Friday. Anthony Collins would replace Smith, who has been among the most-improved players on the team. DE Carlos Dunlap (hamstring), who has been out for four of the past five games, is probable after being limited in practice all week. RB Cedric Benson (back), CB Nate Clements (hamstring), S Chris Crocker (knee) and LB Manny Lawson (ankle) are all probable.

BROWNS: Cleveland finally made it official and ruled out QB Colt McCoy (concussion), who hasn't practiced since getting hit in the head by Steelers LB James Harrison. Seneca Wallace makes his fifth start for the Browns. TE Ben Watson (concussion, placed on injured reserve), FB Owen Marecic (concussion) and SS T.J. Ward (foot) are also out. WR Josh Cribbs (groin) and RB Montario Hardesty (calf) are questionable. RB Peyton Hillis had full practices all week and wasn't listed on the injury report.

RAVENS: CB Lardarius Webb (toe, questionable) is considered the most serious after not practicing all week. Jimmy Smith and Cary Williams are expected to start for Baltimore at cornerback. LB Ray Lewis (toe, questionable) is expected to return after being sidelined for four weeks. DE Cory Redding (ankle, questionable) returned to practice after missing Wednesday and Thursday. DT Haloti Ngata (back, questionable) has been limited all week but should start. K Billy Cundiff (left calf, questionable) didn't practice this week but that was considered precautionary because he kicked last Sunday with the same injury.

STEELERS: Official designations will come out Saturday because the Steelers play on Monday night. QB Ben Roethlisberger (ankle) practiced for the first time this week, although it was on a limited basis. SS Troy Polamalu (hamstring), C Maurkice Pouncey (ankle) and WR Emmanuel Sanders (foot) all didn't practice.
