Colts 20, Chiefs 13: Andrew Luck struggled all day before capping a long scoring drive with a 7-yard touchdown pass to Reggie Wayne with 4:08 to play as visiting Indianapolis clinched a playoff berth.

Luck tied a league record with his seventh game-winning drive of the season, moving his team 73 yards in 13 plays as the Colts (10-5) became the fourth team in history to win 10 games following a two-win season and sewed up the No. 5 seed. Luck boosted his season total to 4,183 yards, eclipsing Cam Newton's (4,051) NFL rookie record.

The top overall draft pick failed to connect on 50 percent of his passes (17-of-35, 205 yards) for the fourth consecutive game but he completed his final six on the game-winning drive. Darius Butler also returned an interception for a touchdown for Indy.

The late heroics by Luck enabled Indianapolis to overcome a stellar effort by Chiefs running back Jamaal Charles, who rushed for 226 yards and had an 86-yard touchdown run in his team's third straight loss.

Peyton Hillis rushed for 101 yards on 15 carries as Kansas City (2-13) churned out 352 yards on the ground and 507 overall one week after they were limited to 119 total yards in a 15-0 loss to Oakland.
