KANSAS CITY, Mo. - The Green Bay Packers' perfect season came to a crashing halt against the struggling Kansas City Chiefs, who had just fired their coach and were starting a new quarterback.

Kyle Orton threw for 299 yards to outduel Aaron Rodgers, and the Chiefs rallied behind interim coach Romeo Crennel for a shocking, 19-14 victory on Sunday that ended the Packers' 19-game winning streak. It was their first loss since Dec. 19, 2010, at New England. Their 19-game streak was second only to a 21-game run by New England in 2003-04.

Green Bay played without leading receiver Greg Jennings and top rusher James Starks because of injuries but can still wrap up home-field advantage throughout the playoffs in their final two games against Detroit and Chicago.

Rodgers was 17 of 35 for 235 yards and a touchdown, and he also ran 8 yards for another TD with 2 minutes, 12 seconds left to play.

But the Packers (13-1) were unable to recover the onside kick, and Kansas City picked up a couple of first downs to secure the victory.

Ryan Succop kicked four field goals for Kansas City (6-8), which had lost five of its last six games and fired coach Todd Haley last Monday. Jackie Battle added a short scoring plunge with 4:53 left, points that came in handy when Rodgers led one last scoring drive.

Neither team seemed as if it wanted to win in the first half. Packers wide receiver Jordy Nelson was hit twice with offensive pass interference, Rodgers was harassed by the Chiefs' weak pass rush, and Green Bay wound up making five first downs.

One of them came when Kansas City's Jeremy Horne ran into Packers punter Tim Masthay, giving them 15 free yards. The Chiefs tried to give Green Bay another gift later on the drive when Mason Crosby missed a 59-yard field-goal attempt, but Kansas City had 12 men on the field.

With another chance from 54 yards, the normally reliable Crosby still pushed the kick right.

Rodgers finished the half 6 of 17 for 59 yards, with a handful of drops between wide receiver Donald Driver and tight end Jermichael Finley.

Green Bay came into the game averaging nearly 36 points, but was held to its lowest total since beating the Chicago Bears by 10-3 in Week 17 last year.

The Packers needed to win that game to make the playoffs and wound up riding the momentum to a Super Bowl victory over the Pittsburgh Steelers.
