KANSAS CITY, Missouri (AP) ― Mike McCarthy never put a whole lot of stock in a perfect season, except as a means of gaining home-field advantage and setting the Green Bay Packers up for another Super Bowl run.

Well, they still have a chance to earn home-field advantage.

The perfect season? That’s history.

Kyle Orton threw for 299 yards to outduel Aaron Rodgers, and the Kansas City 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.

“I personally always viewed the undefeated season as, really, just gravy,” McCarthy said. “The goal was to get home-field advantage and win the Super Bowl. That’s what we discussed.

“We were fortunate enough to be in the position to possibly achieve the undefeated season,” he added, “but we still have the primary goal in front of us, and that’s to get home-field advantage.”

Green Bay, playing without leading receiver Greg Jennings and top rusher James Starks because of injuries, can wrap up the No. 1 seed in their final two games against Chicago and Detroit. But the Packers no longer have the pressure of becoming the second team in NFL history to win a Super Bowl with a perfect record, or extending the second-longest winning streak in league history.

“I think our goal ultimate goal is to win a Super Bowl. The next step is getting that number one seed in the playoffs,” Rodgers said. “We’ve got a home playoff game ― we’ve got a bye secured.” 

Rodgers was 17 of 35 for 235 yards and a touchdown, and he also scampered 8 yards for another touchdown with 2:12 left in the game. 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.

“They had a good game plan,” Rodgers said. “You have to give them credit.”

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 touchdown plunge with 4:53 left in the game, points that came in handy when Rodgers led one last scoring drive.

“Everybody had marked it off as a win for the Packers, but those guys in the locker room, they’re football players,” Crennel said. “They decided they were not going to lay down, they were not going to give up, so they went out and played a tremendous game.”

Neither team looked all that tremendous 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.
