Following their home win over the Titans, the Patriots flew to Wembley Stadium in London for the year's NFL International Series game against the winless Tampa Bay Buccaneers. Five plays into the game, Buccaneers quarterback Josh Johnson was intercepted by Meriweather, who returned it 39 yards for a touchdown. On the ensuing drive, the Buccaneers advanced to the Patriots' 33-yard line before Meriweather again intercepted a Johnson pass, this time at the Patriots' 15-yard line; he returned this one 31 yards. However, the Patriots could not capitalize on the turnover and went three-and-out. Following a Buccaneers punt, the Patriots began a drive with an end-around to rookie wide receiver Brandon Tate, who was active for his first NFL game after spending the first six weeks of the season on the Physically Unable to Perform list; the run went for 11 yards. Two plays later, Brady connected with Moss on a 37-yard pass, which was followed a few plays later with a 14-yard Welker touchdown reception that gave the Patriots a 14-0 lead. After a penalty on the kickoff, the Buccaneers began their next drive at their own 11-yard line and could not advance one yard before punting; the 43-yard punt was returned by Welker 24 yards. Starting from the Buccaneers' 30-yard line, the Patriots moved to the 11-yard line before Brady was intercepted by safety Tanard Jackson in the end zone early in the second quarter. Following a Buccaneers three-and-out, Brady threw a short pass to Aiken that turned into a 54-yard scoring strike, extending the Patriots lead to 21-0. After another Buccaneers punt, Brady was intercepted by Aqib Talib on a deep pass intended for Brandon Tate; Talib returned it to the Buccaneers' 41-yard line. The 0-6 Buccaneers could not cross midfield though, and were forced into another three-and-out. On a 4th-and-2 from their own 46-yard line, the Patriots attempted a fake punt that was negated by a false start on Mankins; this set up a 26-yard Hanson punt. With less than three minutes remaining in the half, the Buccaneers drove into Patriots territory and then completed two passes to wide receiver Antonio Bryant; the second went for 33 yards and a touchdown, cutting the Patriots' lead to 21-7. The Patriots could not advance the ball on their ensuing drive and punted; two plays later, on the final play of the half, Butler intercepted Johnson at the Patriots' 11-yard line. The Patriots began the second half with a 10-play, 73-yard drive that was capped off with a 35-yard touchdown pass to Watson from Brady. After an exchange of punts, the Buccaneers embarked on a drive that extended into Patriots territory but stalled at the 37-yard line, resulting in a punt. This was followed by two more three-and-outs, before early in the fourth quarter the Patriots completed a 10-play, 89-yard drive with a 1-yard Maroney touchdown run, increasing the Patriots' lead to 35-7. After another Buccaneers punt, the Patriots advanced past midfield before punting after the two-minute warning. On an ensuing 4th-and-7 conversion attempt, Johnson was strip-sacked by Derrick Burgess to set up two Patriots kneeldowns to end the game. The Patriots bettered their record to 5-2 entering their bye week, while the Buccaneers remained winless at 0-7.
