FOXBOROUGH, Ma. – Shane Steichen wasn't going to mess around with overtime.

After Anthony Richardson connected with wide receiver Alec Pierce for a touchdown with 12 seconds to go, Steichen kept the Colts' offense on the field for a two-point try that would either win or lose the game. Richardson powered his way into the end zone to earn the Colts a 25-24 victory.

The fourth down touchdown and two-point conversion capped a heroic 19-play drive on which Richardson completed two passes and rushed for a first down on fourth down to keep the Colts' possession – and, realistically, playoff hopes – alive.

The win improved the Colts' record to 6-7 heading into their bye week. It was the team's first win at Gillette Stadium since 2006.

The Patriots took a 16-14 lead into halftime thanks to ending all five of their first possessions in the first two quarters with a touchdown or field goal attempt. Kicker Joey Slye connected on field goals from 35, 31 and 54 yards before missing a 25-yarder just before halftime; quarterback Drake Maye completed a 16-yard touchdown to tight end Austin Hooper for New England's lone touchdown in the first 30 minutes.

Richardson found running back Jonathan Taylor for a seven-yard touchdown and ran in a three-yard score to account for the Colts' scoring in the first half. He was intercepted when linebacker Jahlani Tavai tipped a pass over the middle, with linebacker Christian Elliss coming down with the pick. New England turned that interception into Slye's 54-yard field goal.

The Colts took the lead to open the second half with a 13-play drive, with 10 of the 12 offensive plays on the possession being rushes. The drive stalled inside New England's 10-yard line, though, leading kicker Matt Gay to knock in a 25-yard field goal.

New England marched downfield on their next possession, with several efficient and explosive plays moving the ball inside the Colts' red zone. Safety Julian Blackmon came up with a massive play, though, when he ripped a bobbling ball out of the grasp of tight end Hunter Henry in the end zone for an interception.

An offensive pass interference penalty assessed to wide receiver Michael Pittman Jr. erased a completion to tight end Drew Ogletree that would've resulted in a first down on the Colts' ensuing possession, ultimately leading to a three-and-out punt.

The Patriots took over at their own 46-yard line and converted the advantageous field position into a go-ahead touchdown. A third-and-three completion to Hooper moved the chains in the red zone, then running back Antonio Gibson rumbled for an 11-yard touchdown. Maye found wide receiver Demario Douglas to convert the two-point try, putting the Patriots up by seven with 8:43 left.

All of New England's first eight drives entered Colts territory; six of seven reached the red zone.

Richardson was picked off by cornerback Christian Gonzalez two plays into the Colts' ensuing possession. The Colts' defense forced a three-and-out, leading to the Patriots' first punt of the game and Richardson and the offense taking over at their own 20-yard line.

Richardson completed a fourth-and-three pass to tight end Mo Alie-Cox to move the chains with just over three minutes left. A third-and-2 deep ball to wide receiver Adonai Mitchell fell incomplete, setting up a critical fourth-and-two on the Patriots' 41-yard line after the two-minute warning. Richardson took a quarterback sweep for a six-yard gain and a first down.

A pass interference penalty then moved the ball to the New England 20-yard line with 78 seconds left. Taylor plunged forward for a first down with 28 seconds left, and Richardson ran down to the Patriots' two-yard line, setting up three plays to either tie or win the game. It took until fourth down, but Richardson got the job done – then won the game.
