Denver, Colorado - The Indianapolis Colts grinded out a gritty 12-9 overtime win on the road against the Denver Broncos on Thursday night, with neither team scoring a touchdown in the game.

In an ugly offensive showing, the teams combined for 12 punts, six fumbles, and four interceptions, heading into halftime with a 6-3 Broncos lead thanks to a pair of Brandon McManus field goals.

The Broncos had a chance to run out the clock and ice the game, but instead called a pass play, with quarterback Russell Wilson throwing his second interception of the game to keep the Colts alive.

They would march down the field for a Chase McLaughlin field goal with five seconds remaining in regulation to tie the game at 9-9 and force overtime, and he would kick his fourth field goal of the night in overtime to take the lead.

Needing a field goal to extend the game or a touchdown to win it, the Broncos finally mounted a strong drive with long completions to Melvin Gordon and Jerry Jeudy to move into the redzone.

When presented with a fourth-and-one on the five-yard line, they went for it instead of kicking another field goal to tie, and failed to convert a pass into the endzone.

It was a miserable day for both quarterbacks as their offensive lines struggled to keep them upright, with the Broncos sacking Matt Ryan six times while Wilson absorbed four sacks of his own. Ryan finished up completing 26 of 41 passes for 251 yards and two interceptions, while Wilson completed 21 of 39 for 274 yards and two interceptions.

Defensively, Caden Sterns had both interceptions for the Broncos, while teammate Bradley Chubb had two-and-a-half sacks, but Colts cornerback and former NFL Defensive Player of the Year Stephon Gilmore proved to be the game-winner.

Gilmore secured the crucial interception to give the Colts a chance, and was then credited with his second pass break-up on the final play of the game to deny the Broncos the winning touchdown.
