KANSAS CITY, Mo. — There were statistics that provided insight about how the Raiders offensive line played against the Kansas City Chiefs on Sunday, but quarterback Carson Palmer wanted to talk laundry.

“I don’t think my jersey needs to be washed,” Palmer said after a 26-16 win over the Chiefs at Arrowhead Stadium.

A week after the Jacksonville Jaguars front seven came off a bye week as if they were in starting blocks and got the better of the Raiders up front, a Kansas City team also coming off a bye was essentially stonewalled.

Kansas City outside linebackers Justin Houston and Tamba Hali, who came in with 10 combined sacks, were nonfactors against left tackle Jared Veldheer and right tackle Willie Smith. The Chiefs got little push up the middle.

Offensive coordinator Greg Knapp called for maximum protection schemes which kept the Chiefs outnumbered, and Palmer was never sacked.

“I think our offensive line did an outstanding job as far as protecting the quarterback,” coach Dennis Allen said. “They’re banged up pretty good right now. I was proud of the way they competed for four quarters today.”

Center Stefen Wisniewski said the line as a unit felt much better walking off the field against Kansas City than it did against Jacksonville, even though both were wins.

“Keeping Carson clean is super important for us, and their D-ends are some of the best in the league,” Wisniewski said. “They got high sack numbers, and to keep those guys off of Carson all game is huge for us.”

Equally gratifying was helping the Raiders control the game in the fourth quarter on the ground, with running back Darren McFadden gaining 75 yards on 12 carries to finish with 114 yards on 29 attempts.

“Running the ball and running it well is pretty boring for a crowd, and if you can have those long, slow drives, it will quiet them,” Wisniewski said.

It was McFadden’s second 100-yard game of the season, and it started slowly with 12 carries for 17 yards at halftime and 17 carries for 41 yards through three quarters. “It took us awhile to get going, but we finished the game out well,” McFadden said. “With our offense, you have to stick with it. You’re going to get 1 or 2 yards here and there, and eventually they’re going to start popping.”

Free safety Matt Giordano had an interception against starter Brady Quinn to set up a Sebastian Janikowski field goal and Pat Lee had an interception against Matt Cassel in the second half deep in Raiders territory, the first pick of his five-year career. Both fumble recoveries by the Raiders were essentially gifts — a muffled punt by Javier Arenas recovered by Jon Condo and a fumbled snap by Cassel recovered by Tommy Kelly.

Wide receiver Denarius Moore has caught touchdown passes in three consecutive games and has established himself as the player Palmer looks to for big plays. “I think everyone knows that he’s the man in our locker room, but I don’t know if guys around the league know about him yet,” Palmer said. “He’s young and has had some injuries, but he is finally healthy.”

Janikowski’s four field goals make him 32 for 36 lifetime at Arrowhead. Two of those misses came in his first game as a rookie in 2000. He missed from 37 yards in the fourth quarter, only to get a second chance because the Chiefs were offsides. He converted from 32 yards.
