The Kansas City Chiefs finally got the best of the Oakland Raiders at Arrowhead Stadium.
Jamaal Charles ran for two touchdowns, the Kansas City defense harassed Terrelle Pryor into throwing three second-half interceptions and the Chiefs remained unbeaten with a 24-7 victory Sunday.
After winning just twice last year, Kansas City (6-0) pressed on with the second-best start in franchise history. The Chiefs won their first nine games during the 2003 season.
The Chiefs piled up 10 sacks while ending a three-game skid to the Raiders (2-4), and a six-game losing streak to them at Arrowhead Stadium. They also held Darren McFadden to 52 yards rushing.
Pryor threw for 216 yards and a touchdown, but his interceptions proved costly.
The first led to Charles' go-ahead touchdown in the third quarter, and the second led to Ryan Succop's 33-yard field goal late in the fourth quarter. Husain Abdullah returned the final interception 44 yards for a touchdown with 1:35 left in the game.
Chiefs fans also broke the record for loudest outdoor sports stadium, set earlier this year by the Seahawks.
According to the Chiefs, the noise level hit 137.5 decibels — roughly the sound of a jet engine — making their presence known.
Pryor and his patchwork offensive line struggled to deal with the crowd noise, especially in the second half.
On one possession, Pryor was twice whistled for delay of game partly because third-string center Mike Brisiel couldn't hear him. Oakland also had a false start on the same drive.
The Raiders finished with 11 penalties for 68 yards.
Oakland actually struck first in the second quarter when Denarius Moore beat Chiefs defensive back Marcus Cooper, starting in place of the injured Brandon Flowers, on a quick slant over the middle. Moore caught the pass from Pryor in stride and went 39 yards for the touchdown.
It remained 7-0 until the waning minutes of the first half, when the Chiefs took over at the Oakland 45. Pass interference on the Raiders' D.J. Hayden on third-and-10 kept the drive alive, and Charles squirmed the 7 yards for the tying score with 1:06 left.
The Chiefs were poised to take the lead early in the third quarter, but Hayden stripped Charles of the ball inside the Oakland 10 and Charles Woodson recovered it.
But the Raiders gave it right back when Kansas City brought a blitz and Pryor lobbed a pass off his back foot that Quintin Demps picked off.
Five plays later, Charles plunged into the end zone to give the Chiefs a 14-7 lead.
The way their defense was playing, that proved to be enough. Kansas City kept up the heat on Pryor the rest of the way — on one drive, two penalties and two sacks left the Raiders facing fourth-and-48 at their 12. Not even their punt made it to the first down marker.
Cooper's interception set up Succop's field goal with 2 minutes left to put the game out of reach, and Abdullah's pick-6 left the crowd packed inside Arrowhead Stadium rocking at the end.
