The Raiders officially exited the playoff race Sunday courtesy of Jamaal Charles, who scored five touchdowns in a 56-31 win by the Kansas City Chiefs at O.co Coliseum.
In falling to 4-10, the Raiders were buried under an avalanche of turnovers, with Matt McGloin throwing four interceptions and the Raiders losing a pair of fumbles on a poor shotgun snap from center and on a kickoff return by Taiwan Jones.
The Raiders finished with seven turnovers in all, as Terrelle Pryor threw a late interception to Ron Parker.
Charles, a running back who the Raiders have been able to handle on the ground, destroyed the Oakland defense with touchdown receptions of 49, 39, 16 and 71 yards from Alex Smith and also had a 1-yard touchdown run.
Kansas City, which clinched a playoff berth at 11-3, also got a 6-yard touchdown pass from Smith to Sean McGrath and a 17-yard touchdown run from Knile Davis. It was the most points ever scored against the Raiders.
The Raiders have kept Charles in check on the ground, but found covering him on pass plays next to impossible. Charles finished with eight receptions for 195 yards and scored his first three touchdowns on perfectly executed screen passes.
Smith finished 17 of 20 for 287 yards, five touchdowns and no interceptions before giving way to Chase Daniel with the game safely in hand.
The Raiders, who got within 35-31 in the third quarter after trailing 35-10, had two 1-yard run by running back Rashad Jennings and touchdown passes of 18 and 14 yards by Matt McGloin to Andre Holmes and Mychal Rivera.
Sebastian Jankiowski also kicked a 34-yard field goal.
McGloin finished 19 of 37 for 297 yards but left in the fourth quarter after being poked in the eye. He twice left while healthy in favor of Pryor.
