KANSAS CITY, Mo. -- One of pro football's most intense rivalries has disintegrated into a one-sided affair.
The Oakland Raiders recorded their sixth consecutive win at Arrowhead Stadium, and their seventh victory in 10 games overall against the Kansas City Chiefs, by taking a 26-16 decision Sunday.
In addition to losing the game, the Chiefs also lost new quarterback Brady Quinn, who suffered a head injury in the first quarter.
He was replaced by Matt Cassel, who had been the starter until he sustained a concussion three weeks ago.
The Chiefs continued to look bad while the Raiders were mediocre, but that was enough for Oakland to become the second visiting team to win six straight games in Kansas City. The Pittsburgh Steelers had a six-game Arrowhead Stadium winning streak from 1974 to 1992.
Oakland (3-4) prevailed Sunday with a better defense than offense, avoiding mistakes such as penalties and turnovers.
Not so for the Chiefs (1-6). Kansas City gave the ball away four times, increasing the Chiefs' turnover total to 25 in seven games.
Desperate for change coming off their bye week, the Chiefs gave Cassel the hook and gave the job to Quinn. However, Quinn completed just two of four passes and was hurt while throwing an interception.
While the Chiefs were stumbling about, the Raiders were not flashy, just methodical in taking advantage of the opportunities they received, turning their takeaways into 13 points.
After throwing an interception on the first offensive play of the game, Oakland quarterback Carson Palmer played well, throwing touchdown passes to wide receivers Denarius Moore and Darrius Heyward-Bey. Sebastian Janikowski added four field goals to the winning equation.
The first half was controlled for 29 minutes by the defenses, as they each allowed only a pair of field goals. For the Raiders, Janikowski hit from 36 and 35 yards, while Ryan Succop made field goals of 30 and 42 yards for the Chiefs.
Janikowski's second field goal was set up by an interception by Matt Giordano. The Oakland safety grabbed Quinn's throw that was intended for tight end Tony Moeaki and returned it 21 yards into Kansas City territory. That was the last time Quinn was seen, as he was taken to the locker room.
The only first-half touchdown came in the last minute of the second quarter when the Raiders recovered the ball after Chiefs return man Javier Arenas muffed a punt. That set up Oakland at the Kansas City 11-yard line, and Palmer took the offense into the end zone on three plays, throwing a 9-yard touchdown pass to Moore. The PAT from Janikowski gave the Raiders a 13-6 lead that they carried into halftime.
In the third quarter, Palmer connected with Heyward-Bey for a 32-yard touchdown play, and Janikowski was good from 29 and 32 yards. The 29-yarder was set up when the Chiefs fumbled a snap. Succop added a 52-yard field goal.
The Chiefs' only touchdown came late in the game when Cassel hit wide receiver Dexter McCluster with a 10-yard pass.
NOTES: The Chiefs were without starting defensive end Glenn Dorsey for the fourth consecutive game due to a calf injury. ... Janikowski has always loved kicking at Arrowhead Stadium. He's now 32-for-36 over his career in Kansas City. ... Oakland's defense shut down Chiefs running back Jamaal Charles, allowing him just 10 yards on eight touches. Charles gained 4 yards on five carries, and he had three receptions for 6 yards. ... The Chiefs have yet to hold a lead in any game this season. During their lone win, Sept. 23 at New Orleans, they won 27-24 on an overtime field goal.
