Chiefs 56, Raiders 31: Jamaal Charles tied a 52-year-old franchise record with five touchdowns from scrimmage and visiting Kansas City forced seven turnovers as it clinched a playoff spot and kept alive its hopes of winning the AFC West.

Alex Smith was 17-of-20 for 287 yards and five touchdowns - four of them to Charles, who caught eight passes for 195 yards - as the Chiefs (11-3) racked up the highest point total in the NFL this season and matched the second-highest total in franchise history. Eric Berry had two of Kansas City's five interceptions, including one he returned 47 yards for a touchdown.

Matt McGloin was 18-of-36 for 297 yards with two touchdowns and four interceptions for the Raiders (4-10), who have lost nine of the last 11 meetings in Oakland. Rashad Jennings rushed for 91 yards and two touchdowns and Andre Holmes had four catches for 58 yards and a score.

The game was marked by wild momentum swings, as Kansas City built a 35-10 lead on four touchdowns by Charles - receptions of 49, 39 and 16 yards and a 1-yard run - and Berry's interception return touchdown only to let the Raiders back in it. Oakland cut it to 35-17 at halftime on Jennings' second TD run of the day and McGloin hit Holmes and Mychal Rivera for TD passes to trim the deficit to 35-31 with 4:57 left in the third.

The Chiefs regained control when Smith and Charles hooked up for a 71-yard touchdown on third-and-1, and a fumble on the ensuing kickoff set up Smith's 6-yard TD pass to Sean McGrath. Derrick Johnson's acrobatic interception - McGloin's fourth of the day - led to Knile Davis' 17-yard TD run to put it away.
