After defeating the Bears and Lions (both winless teams) at home to get to .500, the Seahawks traveled to Cincinnati to take on the 4-0 Bengals. In the 3rd quarter, a 23-yard fumble returned for a touchdown by Bobby Wagner allowed the Seahawks to take a commanding 24-7 lead. The Seahawks, however, allowed the Bengals to score the final 20 points of the game, capped by Bengals kicker Mike Nugent kicking the game-winning field goal in overtime. It's the first time since 2004 that the Seahawks blew a 17-point lead. During that stretch, they were 71-0 when holding a 17-point lead. With the loss, the Seahawks dropped to 2-3. Additionally, they dropped to 0-2 in overtime games (losing both by game-winning field goals).
