Kansas City punctuated the win in style when 346-pound defensive tackle Dontari Poe, lined up at quarterback, threw a jump pass to Demetrius Harris with just under two minutes left. The Chiefs were already assured of a wild card when Pittsburgh beat Baltimore earlier in the day, 31-27. But a win next weekend in San Diego coupled with an Oakland loss in Denver would give the Chiefs their first division title since 2010, not to mention a first-round bye and home playoff game.

Meanwhile, the Broncos trudged through another inept offensive performance. Trevor Siemian was 17 of 43 for 183 yards and a game-ending interception, and the only TD drive he led came after a pick gave him the ball at the Kansas City 6. Justin Forsett scored two plays later. The lackluster performance came one week after a dismal showing in a 16-3 loss to New England led to a locker room shouting match between the Denver offense and defense. The Broncos downplayed any kind of disharmony this week , but their performance on a sloppy, soggy Christmas night at Arrowhead Stadium only seemed to underscore the rift during a most frustrating of seasons.

CLOSING SPEED: The biggest hit of the night came when a security guard tackled a fan that had run onto the field. Of course, it came after the fan already had run untouched about 90 yards, so in that respect the security force wasn’t a whole lot better than the Broncos’ first-half defense.

SCARY MOMENT: Broncos cornerback Kayvon Webster was taken from the field on a cart after getting hit high by Chiefs linebacker Terrance Smith while covering a touchback in the second quarter. Webster’s head was snapped back by the block and he was being evaluated for a concussion. He did not return.

OTHER INJURIES: Broncos defensive end Derek Wolfe left in the first half with a neck injury and did not return. Denver was already without leading tackler T.J. Ward and tight ends Virgil Green and A.J. Derby because of concussions and linebacker Brandon Marshall because of a hamstring.
