Following a shocking loss to the 3-7 Kansas City Chiefs the previous week, the Steelers traveled to M&T Bank Stadium for another divisional game. Ben Roethlisberger, who suffered a concussion in the previous week's overtime loss, was the designated 3rd (emergency) quarterback. Backup Charlie Batch also was hurt in that game, which left 2nd-year QB Dennis Dixon, who previously had one pass in his NFL career, to start. The Steelers received the opening kickoff, but went three-and-out. On the ensuing possession, the Ravens drove down the field with ease, capping off their drive with a touchdown run by Willis McGahee. In the second quarter, Dixon hit WR Santonio Holmes on a play-action pass for a 33-yard TD, tying the game. The Ravens answered on the following drive, with a 52-yard strike from Joe Flacco to Mark Clayton, setting up a 10-yard touchdown pass to Derrick Mason. In the third quarter, on the Ravens opening possession, Mark Clayton made a 9-yard reception but fumbled the ball and it was recovered by Tyrone Carter. The Steelers drove, but were held to a field goal by Jeff Reed. Later in the 4th quarter, Joe Flacco was sacked by Lawrence Timmons and fumbled the ball, recovered by the Steelers near midfield. The drive resulted in a 24-yard run on a QB option by Dixon, giving the Steelers their first lead of the night. On the Ravens next possession Joe Flacco completed a pass to Derrick Mason for 17&#160;yards, and then found Ray Rice for a 44-yard reception, setting the Ravens up inside the Steeler 10&#160;yard line with less than 2&#160;minutes left. Billy Cundiff tied the game with a 24-yard field goal. On the following Steeler possession, Dennis Dixon was nearly intercepted by Lardarius Webb. The Steelers were forced to punt, giving the ball back to the Ravens with about 1:30 left in the game. The Ravens managed to drive to the Steeler 40&#160;yard line, where their drive stalled. With the clock counting inside 10&#160;seconds left and no timeouts, the field goal team managed to get into formation, and get the kick off. The 56&#160;yard attempt by Billy Cundiff was dead center, but about 2&#160;yards short, sending the game into overtime. In overtime, the Steelers won the coin toss and got the ball, but were forced to punt. The Ravens, also forced to punt deep in their own territory, gave the ball to Pittsburgh around the Steeler 40&#160;yard line. On a 3rd and 5, Dennis Dixon threw an interception to LB Paul Kruger, who returned the ball 26&#160;yards to the Steeler 28&#160;yard line. Already in field goal range, the Ravens ran the ball down to the Pittsburgh 11&#160;yard line where Billy Cundiff made a 29-yard field goal to win the game. With their second consecutive overtime loss, the Steelers fell to 6-5.
