Reeling from three straight losses, the Jets made some changes in the lineup, moving Darrelle Revis and inserting Hank Poteat and Abram Elam. QB Chad Pennington got off to a quick start, completing a 57-yard pass to Laveranues Coles. Both New York and Cincinnati were able to move the ball back and forth in the first half, ending the half with the Jets on top 20-10. The fourth quarter would eventually prove to be the Jets undoing, however. After giving up a touchdown in the third quarter to make the score 23-17, the Jets gave up three touchdowns and only scored their last touchdown in the closing seconds of the game, ending with a 38-31 loss. The fourth quarter was marked by many mistakes, including a costly pass interference by Darrelle Revis and a fumble and interception by Chad Pennington. The pass interference kept a Bengals drive alive, and the fumble gave the Bengals the ball at midfield. Finally, with 50&#160;seconds left in the game, Pennington throws a hurried pass into the hands of Bengal Johnathan Joseph, who runs the ball 42&#160;yards for the game-sealing touchdown. After the game, coach Eric Mangini refused to endorse Chad Pennington as the quarterback for next week's game against the Buffalo Bills, stating that he'd "need to look at the tape," indicating a possible change to Kellen Clemens.
