OAKLAND, Calif. — Kyle Boller dropped back on Oakland’s first series and threw a pass to the left sideline that Kendrick Lewis intercepted and returned for a touchdown. Carson Palmer did the same to the right side to Brandon Flowers in the fourth quarter.

After all the talk this week about who would start at quarterback for the Oakland Raiders, it didn’t much matter. Boller and Palmer were equally bad.

Boller and Palmer each threw three interceptions and the Kansas City Chiefs took advantage of the rusty quarterback play to win their third straight game, beating Oakland 28-0 Sunday in their most lopsided road win ever against the Raiders.

“It was just an awful feeling walking off the field to be beat like that in the fashion that we were beat,” said Palmer, who was a retired player at home less than a week ago. “We need to regroup.”

Boller became the first Raiders quarterback in 13 years to throw three interceptions in the first half, including Lewis’ 59-yard score on the first drive of the game for Oakland (4-3). Palmer relieved in the second half and threw three more interceptions, including one that Flowers returned 58 yards to give the Chiefs a 28-0 lead early in the fourth quarter.

Cornerback Javier Arenas and Le’Ron McClain each added touchdown runs for the Chiefs (3-3) on a day the Kansas City offense didn’t have to do much at all.

After being outscored 89-10 in lopsided losses to Buffalo and Detroit to open the season, the defending AFC West champion Chiefs have won three straight to get back into contention in the division race. While the wins came against cellar dwellers Minnesota and Indianapolis and a banged-up Raiders team missing its leading passer, scorer and rusher for most of the game, the Chiefs aren’t apologizing.

“We don’t have too many pretty games, but as long as we come away with the victory that’s all that matters,” said cornerback Brandon Carr, who had one interception. “We’re definitely making progress and trying to keep this thing going.”

The Raiders’ promising season was jolted last week when starting quarterback Jason Campbell was knocked out with a broken collarbone. Coach Hue Jackson moved quickly to get a replacement by trading for Palmer on Tuesday.

Palmer had been working out on his own in Southern California. Because of his rust and unfamiliarity with his teammates and the playbook, Palmer did not start in his debut.

It didn’t end up mattering because neither quarterback was able to do much besides throw interceptions.

Boller was seven for 14 for 61 yards and became the first Raiders quarterback to throw three interceptions in the first half since Donald Hollas in 1998 against Miami. Palmer went eight for 21 for 116 yards with the three interceptions.
