Afterwards, the Jets regained the lead as Feely got a 26-yard field goal, along with safety Abram Elam returning an interception 92 yards for a touchdown.

Buffalo would respond with kicker Rian Lindell getting a 53-yard field goal, yet New York replied with RB Thomas Jones getting a 7-yard TD run.  In the fourth quarter, the Bills tried to rally as CB Jabari Greer returned QB Brett Favre's 300th career interception 42 yards for a touchdown.  Favre subsequently led the Jets downfield on a seven-minute drive, resulting in a 31-yard field goal from Feely to put the game out of reach for Buffalo.
