In the end, it didn’t matter whether the quarterback was Kyle Boller or Carson Palmer.
The Raiders’ secrecy about naming a starter was no mystery to the Kansas City Chiefs, who intercepted six passes Sunday and returned two of them for touchdowns Sunday in a 28-0 AFC West win at O.co Coliseum.
The loss snapped the Raiders’ eight-game winning streak in the AFC West and dropped their record to 4-3 heading into their bye week, where much time will be spent by coach Hue Jackson and offensive coordinator Al Saunders getting Palmer up to speed.
Kansas City, 3-3, has won three straight games, beating a team with a winning record for the first time this season.
The Raiders weren’t helped by the absence of their most explosive player, running back Darren McFadden, who left with an undisclosed injury after carrying twice for four yards and did not return.
Kendrick Lewis got Kansas City started with a 59-yard interception return on Boller’s first pass of the day. Brandon Flowers sent much of the crowd heading for the exits with 14:25 left by stealing a Palmer pass and racing 55 yards for a touchdown.
Palmer had two other interceptions, the last one coming on a deflected pass off the hands by Denarius Moore deep in Chiefs territory by Jon McGraw.
By the time Jackson gave the hook to Boller with 10:25 left in the third quarter, the Raiders trailed 21-0. He completed 7 of 14 passes for 61 yards with three interceptions, including a 59-yard interception return for a touchdown by Kendrick Lewis on his first pass of the day.
There was also a fumbled center snap with Boller’s back to the end zone, which he recovered.
Boller had been getting booed sporadically since the interception, with the level increasing until Palmer put on his helmet with while the Chiefs were in the process of a 66-yard drive that would put them up 21-0.
Besides the Lewis interception, Lewis overthrew Denarius Moore on a pass that was intercepted by Brandon Flowers, with Kansas City then driving 61 yards to score on a 1-yard run by Le’Ron McClain.
The other interception came on a forced pass to Heyward-Bey that Brandon Carr intercepted at the 10-yard line.
Oakland’s best chance to score in the first half was stuffed at the 1-yard line on fourth-and-goal when Michael Bush took a direct snap and was hit by Derrick Johnson.
The Raiders got into position to score on a 35-yard run by Bush.
