Pittsburgh quarterback Ben Roethlisberger has a sprained right shoulder and left Heinz Field with his arm in a sling. His status for Sunday's showdown with AFC North rival Baltimore is uncertain.
Roethlisberger left Monday night's overtime win over Kansas City in the third quarter after getting slammed to the ground by Chiefs linebackers Tamba Hali and Justin Houston.
Veteran backup Byron Leftwich filled in and completed 7 of 14 passes for 73 yards.
Tomlin said safety Troy Polamalu (pah-luh-MAH'-loo) remains doubtful with a right calf injury. Polamalu hasn't played since a win over Philadelphia on Oct. 7.
