Coming off their win over the Buccaneers, the Ravens stayed at home for a Week 13 AFC North rematch with the Pittsburgh Steelers on Sunday night.  Baltimore delivered the game's opening strike in the first quarter as quarterback Joe Flacco found wide receiver Anquan Boldin on a 14-yard touchdown pass.  After a scoreless second quarter, the Steelers responded with kicker Shaun Suisham got a 45-yard field goal.  The Ravens would answer with a 24-yard field goal from kicker Billy Cundiff.  Pittsburgh would get another field goal in the fourth quarter, a 19-yarder by Suisham. In the final minutes of the game, the Ravens were driving, trying to run down the clock, when Troy Polamalu sacked Flacco, forcing a fumble in the process. The Steelers recovered the fumble and returned it to the Ravens' 9-yard line. Two plays later, quarterback Ben Roethlisberger completed a 9-yard touchdown pass to running back Isaac Redman. Baltimore tried to rally, but the Steelers' defense held on to preserve the win.
