Pittsburgh Steelers quarterback Ben Roethlisberger has a sprained right shoulder and his status for Sunday's showdown with AFC North rival Baltimore is uncertain.
Coach Mike Tomlin said Tuesday that Roethlisberger is "questionable" and is waiting for more details on the quarterback's condition. Roethlisberger left Monday night's 16-13 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. Leftwich's last start came in 2009 while playing for the Atlanta Falcons.
Tomlin said safety Troy Polamalu remains doubtful with a right calf injury. Polamalu hasn't played since a win over Philadelphia on Oct. 7.
