Bad time for Steelers' line to get banged up

It shouldn't surprise anyone that safety Troy Polamalu (right calf) has been declared out for Sunday night's game. But there's another concern heading into the AFC North showdown with the Bengals: the Steelers' offensive line.

Right tackle Marcus Gilbert (ankle) has been ruled out and center Maurkice Pouncey (knee) is considered questionable, Steelers coach Mike Tomlin announced Tuesday. Rookie second-round draft pick Mike Adams will make the first start of his career while filling in for Gilbert, and Doug Legursky would start for Pouncey.

While the Steelers have reduced the sacks on Ben Roethlisberger lately, it's the wrong time for Pittsburgh to have a banged-up offensive line. The top five defensive linemen for the Bengals each have at least one sack and have totaled 14 sacks in six games: defensive ends Carlos Dunlap (one sack), Michael Johnson (five) and Robert Geathers (one) along with defensive tackle Geno Atkins (six) and nose tackle Domata Peko (one). The Steelers are going to need to give Adams help in blocking Dunlap.

In other injury news, outside linebacker LaMarr Woodley (hamstring) is expected to play after missing one game. That would mean only one starter -- Polamalu -- would be missing on defense.
