In the first of three straight games against divisional opponents, the Patriots stayed at home to face the Bills, who were looking to avoid ending their own three-game divisional swing without a win. The Bills' opening drive went three-and-out, with a Seymour sack of Bills quarterback Trent Edwards setting up the punt. After a 21-yard Cassel pass put the Patriots in the Bills' red zone, a 13-yard Cassel touchdown scramble gave the Patriots a 7-0 lead. Following an exchange of punts, an errant Edwards throw was intercepted by Hobbs to begin the Patriots' next drive from the Bills' 34-yard line. Seven plays later, a 32-yard Gostkowski field goal extended the Patriots' lead to 10-0 early in the second quarter. Gostkowski's ensuing kickoff went out of bounds; the resulting illegal procedure penalty meant the Bills got the ball at their own 40-yard line. The Bills' drive reached as far as the Patriots' 4-yard line on 2nd-and-goal, but the Patriots' defense did not allow Bills running back Marshawn Lynch any positive yardage on two straight runs. A 25-yard Rian Lindell field goal then cut the Patriots' lead to 10-3. The Patriots' ensuing drive began with a 27-yard Welker reception but could not advance pass the Bills' 31-yard line; a 49-yard Gostkowski field goal attempt was no good. A Bills punt on their next drive gave the Patriots the ball at their own 3-yard line, where the Patriots ran out the clock to end the first half. On the third play of the second half, Welker's six catch of the game made him the first player in NFL history to record six catches in the first nine games of a season. The ensuing 13-play drive culminated with a 37-yard Gostkowski field goal that gave the Patriots a 13-3 lead. An exchange of punts gave the Bills the ball at their own 19-yard line to begin their next drive, which advanced to the Bills' 45-yard line before Edwards' second interception of the day, this one to O'Neal, gave the Patriots the ball back at their own 41-yard line for the final play of the fourth quarter. Five plays later, Cassel was sacked for the only time in the game at the Bills' 44-yard line by defensive lineman Marcus Stroud and safety George Wilson; Stroud forced a fumble in the process and Wilson recovered it at the spot of the sack. The Bills' next drive ended in a Brian Moorman punt that the Patriots the ball at their own 8-yard line with just over 11 minutes remaining in the game. The Patriots then embarked on a 19-play, 92-yard drive that tied a franchise record set in 2002 for number of plays in a single drive; it was also the Patriots' NFL-leading 22nd drive of ten or more plays. It ended with a 1-yard Green-Ellis touchdown run that extended the Patriots' lead to 20-3 with 1:57 remaining in the game. The Bills responded on the ensuing kickoff with an 85-yard return by Leodis McKelvin, setting up a 14-yard touchdown catch by fellow rookie James Hardy on the next play to cut the Patriots' lead to 20-10. The Bills then attempted an onside kick, which appeared to be recovered by the Bills but was then ruled to be dead at the spot as it had been touched by a Bills player before traveling the necessary 10 yards. Three kneeldowns by the Patriots gave them a 20-10 win to better their record to 6-3.
