Steelers quarterback Ben Roethlisberger suffered a shoulder injury in Pittsburgh's 16-13 (OT) win over Kansas City in Week 10, and Steelers coach Mike Tomlin classified his injury as a "shoulder sprain," and is listing him as "questionable" for the Steelers' Week 11 game against the Baltimore Ravens.

He confirmed Byron Leftwich is the "acting starter" in preparation for a Roethlisberger absence, should that be the case.

Tomlin didn't confirm anything new, although reports on the severity and extent of the injury vary. A recent ESPN report is saying it "could be significant."

Roethlisberger had injured his shoulder during the 2011 season, but Tomlin said the recent injury is not related to the old injury, to his knowledge.

Leftwich's last start came in 2009 when he was with the Tampa Bay Buccaneers.

Leftwich struggled under the same pass rush that gave Roethlisberger problems when he played. Roethlisberger had 33 snaps, and Leftwich had 32. Both completed 50 percent of their passes, and Roethlisberger hit Mike Wallace on a seven-yard pass for the Steelers only touchdown of the game.
