Trying to win their first road game in an opponent's stadium for the first time in 2009, the Patriots traveled to Buffalo with a one-game lead in the division. After winning the toss, the Bills received the opening kickoff and began a 14-play, 69-yard drive that elapsed over nine minutes of the first quarter. After the Bills reached the Patriots' 2-yard line on 3rd-and-goal, a false start penalty and an incomplete pass limited the Bills to a 25-yard Lindell field goal. The Patriots' first possession reached midfield before a Brady pass intended for Welker was intercepted by linebacker Paul Posluszny at the Bills' 39-yard line. However, another penalty and two straight sacks set up a Bills three-and-out. The Patriots' next drive spanned into the second quarter, moving 75 yards on 5 plays; the Patriots moved to the Bills' 3-yard line on a 43-yard defensive pass interference penalty on Donte Whitner. Brady then hit Moss in the back of the end zone for a 13-yard touchdown, putting the Patriots ahead 7-3. The Bills offense continued to struggle on their next possession, facing a 2nd-and-23 and a 3rd-and-20 before punting; the Patriots advanced into Bills territory on their next possession before also punting. This time the Bills offense began to move the ball, reaching midfield before quarterback Ryan Fitzpatrick threw an interception to Wilhite at the Patriots' 36-yard line. With 3:30 remaining, the Patriots drove back downfield, and assisted by a 21-yard defensive pass interference penalty, into the red zone. Maroney then ran for a 1-yard touchdown to give the Patriots a 14-3 lead. Following a 41-yard Bills kickoff return, they were able to reach the Patriots' 38-yard line and attempt a 56-yard field goal at the end of the half, but it fell wide left to keep the score at 14-3. Both teams opened the second half with three-and-out punts. The Patriots came back with a 14-play, 64-yard drive that ended on a 30-yard Gostkowski field goal. The Bills, however, responded with a lengthy drive of their own before an offensive holding penalty and two incompletions set up a punt from the Patriots' 38-yard line early in the fourth quarter. After an exchange of four punts, the Bills drove to the Patriots' 12-yard line, before an incompletion, a one-yard run, and two more incompletions turned the ball over on downs. With just over four minutes left in the game, the Patriots were unable to gain a yard net on their next drive, in fact losing one yard in the process, before punting back to the Bills with 3:37 left; a 38-yard punt and a 20-yard return gave the Bills the ball at the Patriots' 28-yard line. After a 17-yard completion to Josh Reed, Fitzpatrick threw an 11-yard touchdown pass to Lee Evans to cut the Patriots' lead to 17-10. The Bills attempted an onside kickoff with 3:02 remaining in the game, which was recovered by the Bills but nullified on an offsides penalty. The Bills then kicked off normally to the Patriots, hoping for a defensive stop. However, on the first play after the two-minute warning, the Patriots converted a third down on an 8-yard pass to Welker, sealing a Patriots victory. The win moved the Patriots to 9-5 on the season and gave them a two-game lead in the division.
