2017 Indianapolis Colts season

The 2017 Indianapolis Colts season was the franchise's 65th season in the National Football League, the 34th in Indianapolis and the tenth playing their home game at Lucas Oil Stadium. It was also the sixth and final season under head coach Chuck Pagano, who was fired at the end of the season. It was also the first under new general manager Chris Ballard, the former Kansas City Chiefs' Director of Football Operations, following the dismissal of Ryan Grigson. The Colts were looking to improve on their 8–8 record from last year and make the playoffs for the first time since 2014. However, star quarterback Andrew Luck suffered an injury before the regular season began and was placed on the injured reserve list, putting the season in doubt.

After an ineffective performance by backup Scott Tolzien in Week 1 against the Rams, the Colts put Jacoby Brissett as their starting quarterback for the rest of the season. However, Brissett could not save the team as they finished 4-12 for their first losing season since 2011, and missed the playoffs for the third consecutive season.

Week 14: at Buffalo Bills
The game in Buffalo, called the "Snow Bowl" by the media, was notable for being held in the midst of a lake-effect snow storm that left over a foot of snow on the stadium's turf in similar weather conditions to games such as the Snowplow Game. The Colts and Bills played a low-scoring affair, tied at 7 by the end of regulation thanks to a fourth quarter touchdown pass from Jacoby Brissett to Jack Doyle. However, LeSean McCoy managed to win the game for the Bills with a 21-yard touchdown run in overtime. The Colts fell to 3–10.

Week 15: vs. Denver Broncos

Week 16: at Baltimore Ravens
The Colts played a close matchup with the playoff-bound Ravens, but it was not enough as the Colts lost and fell to 3-12.

Week 17: vs. Houston Texans
In a battle for the basement, the Colts defeated the Texans 22-13 and swept the Texans for the first time since 2014. The win also secured the Colts third place in the division.
