The Chiefs didn’t rely on help from others on Sunday. They took the field at the Oakland Coliseum knowing they had to beat the Raiders to clinch a playoff spot.

And that’s exactly what they did, defeating the Raiders 56-31 and clinching at least a wild-card spot in the AFC playoffs in the Chiefs’ first season under coach Andy Reid.

Chiefs running back Jamaal Charles scored a club-record-tying five touchdowns -- including an NFL-record four touchdown catches in a game by a running back -- and safety Eric Berry intercepted two passes, returning one for a score and setting up another touchdown as the club ensured their first playoff spot since 2010.

Quarterback Alex Smith completed 17 of 20 for 287 yards, five touchdowns and a perfect 158.3 passer rating.

Charles finished with eight catches for 195 yards, four touchdowns. He finished short of former Chief Curtis McClinton’s NFL-record 213 yards in a game by a running back.

The 56 points were three shy of the club record 59 set in 1963 at Denver.

The victory also moved the Chiefs, 11-3, into a first-place tie in the AFC West with Denver, though the Broncos own the head-to-head tie-breaker with two games to go.
