Kansas City won their first five games but lost six of its last seven games.
The Kansas City Chiefs finally righted the ship and will stay atop the AFC West no matter what happens in the Chargers game this afternoon.
Cooper had no receptions on only one target in the first half. Already down double-digits to Kansas City, the Raiders need every win they can get to keep pace in a crowded AFC playoff race. They capitalized when kicker Harrison Butker connected on a 53-yard field, giving the Chiefs a 3-0 lead. Oakland made it interesting late, but fell behind too far to make the late-game run.
Kansas City took advantage of the turnover, putting three more points on the board.
The Chiefs took a 26-0 lead late in the third quarter and held it until well into the fourth before the Raiders came up with a few late scores.

The weather forecasting service said there was a risk of possible travel delays due to wintry conditions on Friday and Saturday. The previous Atlantic storm, named Brian, hit Ireland in late October, less than a week after what began as Hurricane Ophelia.
Cornerback Terrance Mitchell drew the start in Peters' place, intercepting a pass and breaking up three others.
Neither was Carr, the Raiders' $125 million quarterback who has not looked the same, really, since suffering a broken pinkie finger on his passing hand previous year, let alone his broken right leg in Week 16 last season or the broken bone in his back he suffered at Denver in Week 4 this season.
NOTES: Oakland WR Amari Cooper left the game after aggravating an ankle injury midway the rough second quarter. He completed 24 of 41 passes for 200 yards.
The Raiders' defense supplied some pass rush in the game early, and they collected their second and third interceptions of the season in this game. A handful of unforced errors by the Chiefs kept the score from being 38-0 entering the final frame after another desultory effort by the Raiders in a big game. Quarterback Derek Carr has been wildly inconsistent after an MVP-type campaign last season, and running back Marshawn Lynch only first showed off his "Beast Mode" form in last week's win over the New York Giants, when he rushed for 101 yards - the first time he rushed for over 76 yards this season.
