The Patriots traveled to Indianapolis for a Sunday night game with the Colts in Lucas Oil Stadium. Both teams went three-and-out to start the game, setting up a Colts possession that began from their own 9-yard line. The Colts then went 91 yards on a 15-play drive that lasted over nine minutes, included six first downs, and culminated in a 12-yard Anthony Gonzalez touchdown pass from Peyton Manning to give the Colts a 7-0 lead. The Patriots responded with a 13-play, 56-yard drive of their own that brought the game into the second quarter. Part way through the drive, the Patriots employed the same "Wildcat" formation concept used against them earlier in the season against the Dolphins, using Faulk as the back receiving the direct snap on a run for five yards. The Patriots reached as far as the Colts 11-yard line but could not advance any further; a 29-yard Gostkowski field goal cut the Colts' lead to 7-3. After a Colts punt, the Patriots began their second drive of the game and were able to move the ball 61 yards on 13 plays to as far as the Colts' 17-yard line. The possession saw another use of the "Wildcat" formation; this time Faulk threw to Welker off the direct snap, but Welker then was tackled for a two-yard loss. Two plays later, Gostkowski hit a 35-yard field goal to trim the Colts' lead to 7-6. The Colts began their next drive from their own 18-yard line with one timeout and 1:22 remaining in the first half. A 26-yard Marvin Harrison reception put the Colts in Patriots territory, but Harrison was injured on the tackle and was unable to step out of bounds to stop the clock. Manning spiked the ball at the Patriots' 26-yard line with one second remaining, but was called for a false start; by rule, the penalty incurred a ten-second clock run-off to end the first half. The Patriots' opening drive of the second half spanned 72 yards and nearly eight minutes but also ended with the Patriots having one timeout to use thereafter. On a Faulk run for no gain part way through the drive, the Patriots challenged that the Colts had too many players on the field, contending a Colts player substituting out of the game was unable to get off the field in time. The challenged failed, costing the Patriots their first timeout of the second half. Seven plays later, the Patriots used their second timeout of the half. A 6-yard Green-Ellis touchdown run put the Patriots ahead 12-7, but a two-point conversion attempt on a Faulk run kept the Patriots' lead to five points. A 39-yard Pierre Gar&#231;on return on the ensuing kickoff set up the Colts' next drive to begin from their own 43-yard line; nine plays later, Gonzalez's second touchdown reception of the night, this one from 9 yards out, put the Colts ahead 13-12. The Colts also went for the two-point conversion, and were successful, with a Reggie Wayne catch extending the Colts' lead to 15-12. The Patriots responded with a 15-play, 69-yard drive that brought the game into the fourth quarter, but one which included a dropped would-be touchdown catch by Gaffney on the penultimate play of the third quarter. On a 3rd-and-11 from the Colts' 17-yard line, Cassel completed a pass to Welker for 10 yards; the Patriots initially brought Cassel and the offense back out onto the field for a fourth down conversion try, but Belichick decided against it and called the Patriots' final timeout of the game. A 25-yard Gostkowski field goal then tied the game at 15. Four plays into the Colts' next possession, a third down Gonzalez catch went for 24 yards and put the Colts in Patriots territory. The Colts were unable to make a first down and called upon former Patriots kicker Adam Vinatieri for a 52-yard field goal. The kick was good, and it put the Colts ahead 18-15 with just over eight minutes to play in the game. The Patriots next drive reached Colts territory on a 16-yard David Thomas catch. Two plays later, on a 2nd-and-2 from the Colts' 32-yard line, the tight end committed an unnecessary roughness penalty after a Green-Ellis run to set up a 3rd-and-16 from the Colts' 46-yard line. Faulk gained one yard on a pass from Cassel, setting up a 4th-and-15 where Cassel threw an interception to Colts safety Bob Sanders. A 14-yard Harrison catch on the Colts' next possession gave them a fresh set of downs, and the Patriots, without any timeouts, did not receive the ball again until after a Colts punt with just over 21 seconds left in the game. After two incomplete passes, Cassel completed a pass to Moss, who proceeded to fumble on a lateral attempt. The fumble was recovered by Colts cornerback Tim Jennings to end the game and bring the Patriots' record to 5-3.
