The Baltimore Ravens (7-2) will travel to Pittsburgh Sunday night to take on the Steelers (6-3) in what could be a division-defining game for the 2012 season.
The matchup is the first of two that will occur over the next three weeks. The winner Sunday night may hold their division destiny in their hands.
However, one injury defines this matchup.
The Steelers' attempt to pull even with the Ravens in the AFC North will have to be completed without quarterback Ben Roethlisberger, who is out with shoulder and rib injuries. Pittsburgh will start Byron Leftwich at quarterback Sunday night.
A win for the Ravens over Leftwich would give Baltimore a two-game cushion in the division—plus the tie-breaker—with six games to go in the season.
In the following slides, we break down the matchups that will decide Sunday night's AFC North clash.
