Coming off a divisional win at home over the Bills, the Patriots traveled to Paul Brown Stadium for a matchup with the Bengals. On the game's opening drive, the Patriots drove 66&#160;yards on 11 plays, stalling at the Bengals' 13-yard line before Gostkowski hit a 31-yard field goal. The Bengals' next drive would span five plays but only one yard, ending in a punt. After an exchange of punts, the Patriots began a drive from their own 35-yard line, but quickly advanced into Bengals territory on a 49-yard Morris run. Three plays later, Brady hit Vrabel on a 1-yard touchdown pass to extend the Patriots lead to 10-0. After a Bengals punt on the first play of the second quarter, the Patriots had the ball but found themselves in a 3rd-and-23 situation, when Brady was intercepted by Leon Hall at the Bengals' 35-yard line. The Bengals capitalized on the turnover, with Carson Palmer ending a five-play drive on a 1-yard touchdown pass to T. J. Houshmandzadeh. The Patriots responded by going on a 12-yard, 62-yard drive, finishing it with a 7-yard Moss touchdown reception, putting the Patriots ahead 17-7. The Bengals managed to reach the Patriots' 20-yard line on their next possession, but a Samuel interception at the 2-yard line kept the Bengals from scoring at the end of the first half. The Bengals reached midfield on the opening drive of the third quarter before punting. From their own 19-yard line, the Patriots moved deep in Bengals territory after a 15-yard penalty was tacked onto a 16-yard Moss catch. A few plays later, Morris ran for his second touchdown of the night; the 7-yard run opened the Patriots lead to 24-7. The Bengals, though, continued to threaten the Patriots offensively, moving to the Patriots' 22-yard line before linebacker Tedy Bruschi tipped a third-down pass to force a 40-yard Shayne Graham field goal. The Patriots next drive spanned into the fourth quarter but a Morris run on third down from the Bengals' 13-yard line was stopped for a loss, setting up a 36-yard Gostkowski field goal. Yet again, the Bengals moved into Patriots territory on their ensuing drive, but the Patriots defense prevented another touchdown and forced a 48-yard field goal, making the score 27-13. On the Patriots' next drive, a 23-yard Stallworth catch put the Patriots in Bengals territory, setting up a 14-yard touchdown pass from Brady to Moss. Down 34-13, the Bengals continued to move the ball with a 17-yard Houshmandzadeh catch on the next play, but Palmer's next pass attempt was intercepted by Randall Gay at the Patriots' 47-yard line. The Patriots then ran out the clock to end the game and bring their record to 4-0.
