The Oakland Raiders continued to slide out of the AFC playoff picture Sunday with a 40-9 loss to their division rival Kansas City Chiefs.
Patrick Mahomes threw for a touchdown and ran for a touchdown, Juan Thornhill returned a pick 46 yards for another score, and Kansas City seized control of the AFC West.
LeSean McCoy and Darwin Thompson also had TD runs for the Chiefs (8-4), who took a two-game lead over the Raiders by finishing off a season sweep. That means Kansas City can clinch a fourth straight division title with a win over New England and an Oakland loss to Tennessee next weekend.
Oakland (6-6) sure didn't play like a team fighting for a piece of the division lead.
Derek Carr dropped to 0-6 at Arrowhead Stadium with another miserable outing, throwing for 222 yards with a touchdown and two interceptions. The Raiders failed to score twice in the red zone, were penalized 12 times for 99 yards, and seemingly quit when Kansas City put together a 9 1/2-minute drive almost entirely on the ground that soaked up most of the fourth quarter.
When the Raiders finally scored a touchdown in the last minute, the Chiefs blocked the extra point and returned it for two points -- one more insult to Oakland in a game full of them.
It was the Raiders' seventh straight loss in Kansas City, and the continuation of a major late-season spiral. The blowout came on the heels of a 34-3 loss to the Jets last weekend.
Josh Jacobs was Oakland's lone bright spot, running for 104 yards on 17 carries.
Both teams struggled to move the ball at times with frosty winds whipping at 40 mph out of the west. Flurries even fell during halftime, adding to the misery for fans huddled in the stands.
As if those dressed in silver and black weren't depressed enough.
In the first half alone, Carr threw both of his interceptions. The Raiders lost a fumble on a kick return; failed to convert on fourth-and-1; committed seven penalties; and watched Daniel Carlson yank a 44-yard field-goal attempt about 20 yards wide left.
The Chiefs took advantage of all the squandered opportunities.
Mahomes, who perhaps more than anyone benefited from a week off, capped a 47-yard drive in the first quarter with a short TD pass to Darrel Williams. Then, late in the first half, the reigning MVP scrambled to his left and ran untouched 13 yards for another touchdown.
The Chiefs put the game out of reach in the third quarter.
First, they moved swiftly downfield on the opening possession before Harrison Butker drilled a 50-yard field goal into the wind. Then, on their next possession, Mahomes threw a pick in the end zone that was overturned when replay showed wide receiver Demarcus Robinson was held on the play.
The penalty gave Kansas City the ball back and McCoy scored moments later.
Oakland finally ended the Chiefs' streak of 59 straight points against them when Carlson hit a chip-shot field goal in the fourth quarter. The streak dated to their Week 2 matchup and was a record for a 122-game series that traces its roots to the earliest days of the AFL.
It was also ended the Raiders' streak of 15 drives against Kansas City without a point.
