INDIANAPOLIS (AP) - Mike Hart still has some of those old Michigan moves in his back pocket.
With an overpowering 11-yard touchdown run on the last of his career-high 11 carries, the third-year running back scored in relief of the injured Joseph Addai to give Indianapolis a 19-9 victory over previously unbeaten Kansas City.
It's the first time since 1970 that no NFL team reached 4-0.
The Colts (3-2) won in atypical fashion. For the first time this season, Peyton Manning failed to top 300 yards or throw for a touchdown. He finished 26-of-44 for 244 yards with one interception and couldn't get the Colts into the end zone until Hart's win-clinching score with 4:02 to go.
Addai left midway through the third quarter with what appeared to be a right shoulder injury. He did not return.
Kansas City (3-1) never did get in the end zone.
Jamaal Charles carried 16 times for 87 yards, and Matt Cassel was 16-of-29 for 156 yards. The Chiefs had to settle for three field goals and lost a chance for a miracle comeback when Ryan Succop missed a 51-yard attempt with 1:17 to go.
But this was all about the defenses, which played like they had something to prove.
Only Minnesota and Kansas City had held each of their previous opponents to 14 points or fewer. The Chiefs nearly did it a fourth straight time against one of the league's highest-scoring offenses by forcing the Colts to settle for four field goals before Hart finally punched it in.
Indy, meanwhile, was trying to show it could stop the run and keep foes out of the end zone. The Colts succeeded on one front - limiting the Chiefs to three field goals and no TDs. But Kansas City still ran 27 times for 113 yards.
The difference was Kansas City's failed gambles.
Coach Todd Haley opened the game with an onside kick that didn't go the necessary 10 yards. Nine plays later, Adam Vinatieri hit a 20-yard field goal.
On the next series, Haley went for it on fourth-and-2 from the Indy 8 and Cassel's pass fell incomplete.
Manning took advantage, setting up Vinatieri for a 24-yard field goal that made it 6-0 less than five minutes into the game.
From then, it was essentially a stalemate. Succop hit a 45-yard field goal with 2 seconds left in the first half to make it 6-3.
After Vinatieri opened the second half with a 47-yarder, Succop hit from 35 and 43 yards out, the second after Manning's interception, to tie the score 9-9 late in the third quarter.
Manning made amends quickly, taking the Colts 60 yards on the next series and getting Vinatieri into position for his fourth field goal of the day, a 42-yarder with 14:40 left in the game to give Indy a 12-9 lead.
