Steelers injury report: Ben Roethlisberger has 'unusual' shoulder injury

After Ben Roethlisberger hurt his shoulder Monday night against the Kansas City Chiefs, the Pittsburgh Steelers could be missing their starting quarterback, running back, and one of their top wide receivers Sunday against the Baltimore Ravens.

It's not yet clear how long Roethlisberger will be out with the shoulder problem, or if he'll miss any time at all. Initial media reports were mixed on whether he had a sprained shoulder or a separated shoulder. Jason Cole of Yahoo! reported that the injury was "unusual," although it wasn't evident whether that was a good or bad thing. What is clear is that he'll need more tests Tuesday after leaving the game in the third quarter Monday night with an injury to his throwing shoulder, walking off the field before being carted out of the stadium and taken to a local hospital.

The offense didn't look great after Roethlisberger left, only scoring six points, three after receiving great field position off a Lawrence Timmons interception. But it hadn't looked good while Big Ben was playing, either, on a cold, rainy Pittsburgh night. Both Roethlisberger and his backup, Byron Leftwich, completed 50 percent of their passes, with Leftwich's average attempt going for 5.2 yards to Roethlisberger's 4.7.

The list of injured Steelers continued to players who sat out this past week: Antonio Brown, Rashard Mendenhall, and Troy Polamalu are all questionable for next week's game. Brown was initially reported as having a mild high ankle sprain, but the injury has since been thought to be more serious and possibly cost him more than just the week. Mendenhall and Polamalu have been out for several weeks with Achilles and calf injuries, respectively, but were given Sunday against Baltimore as a possible return date even before the game against the Chiefs. Both will want to make sure they're fully rehabbed after reach coming back from other injuries earlier in the season, Polamalu having actually aggravated his injury.

Linebacker Stevenson Sylvester is also questionable for Sunday's game.
