INDIANAPOLIS – It was not pretty, but add it up after 60 minutes and the Colts will be wearing their white jerseys at least one more time this season.
A Reggie Wayne seven-yard touchdown reception with just more than four minutes remaining gave the Colts a 20-13 lead at Kansas City, and the defense made it hold up as the 10th win for Indianapolis (10-5) clinched a playoff berth.
The Colts jumped out to a 13-3 halftime lead thanks to cornerback Darius Butler returning an interception 32 yards for a touchdown early in the first quarter.
It was Butler's second interception returned for a touchdown this year, and the score tied a Colts club record with a total of four on the season.
Any chance for a second half without drama quickly was put to rest as the Chiefs (2-13) came out and tied the game with 6:00 minutes remaining in the third quarter.
Jamaal Charles cut into the deficit on the first play of the half with an 86-yard touchdown run, the longest rush allowed in franchise history. Ryan Succop hit a 47-yard field goal moments later to tie the game.
With the offense struggling to sustain drives, it was the Indianapolis defense that stood tall with a stand.
The Chiefs were stuffed on a fourth-and-one in Colts territory early in the fourth quarter, and the momentum carried over to offensive side of the ball.
The Colts embarked on a 13-play, 73-yard drive that was capped off when quarterback Andrew Luck found Wayne in the back of the end zone for the game-winning score.
For the season, the Colts were 4-4 on the road and moved their record to 9-1 in one-possession games.
Luck also set an NFL rookie record for a season with 4,183 passing yards.
Defensively, the Colts forced three turnovers, with inside linebacker Pat Angerer causing a fumble in the first half.
Cornerback Vontae Davis recorded his first interception in a Colts uniform in the third quarter, thwarting another Chiefs drive in Indianapolis territory.
Bruce Arians tied an NFL record with nine wins as an interim head coach. Arians tied the marks set by Hamp Pool of the Rams in 1952 and Wally Lemm of Houston in 1961.
Indianapolis will close out the regular season next Sunday when the Houston Texans (12-3) head to Lucas Oil Stadium.
