Input (English): Passage: October 2, 2011 at Paul Brown Stadium, Cincinnati, Ohio (Blacked Out) After two losses, the Bengals played the Buffalo Bills at home with 41,142 people in attendance. Simpson was able to play this game, despite being under investigation for marijuana. Prior to this game, the Bengals lost 10-straight games to the Bills, dating back to the 1988 AFC championship game. After two possessions resulting in punts, the Bengals got a field goal in the first quarter. In the second quarter, the Bills scored three times. Kicker Rian Lindell kicked a 43-yard field goal. In the next Bengals possession, Dalton threw an interception, which was returned for a touchdown. The Bills' running back Fred Jackson scored a 2-yard rushing touchdown for the team to be up 17-3 going into half time. Nugent kicked a field goal, and Gresham caught a touchdown pass in the third quarter to make the score 13-17 going into the final quarter. Lindell kicked a field goal on the Bills' opening drive to make the score 20-13. Dalton had a three-yard rushing touchdown two possessions later to tie the game at 20-20. On the Bengals' final possession of the game, on third-down-and-three-yards-to-go, Dalton scrambled and attempted to make the first down. He was originally called short the referee, but the call was reversed once the play was reviewed. Nugent kicked a game-winning field goal as time expired to beat the Bills 23-20. The win by the Bengals snapped a 10-game losing streak to the Bills. The Bengals had not beaten the Bills since the 1989 AFC Championship Game.
