The Chiefs jumped out to a 21-7 lead at the end of the first quarter, consisting of a 10-yard touchdown run by quarterback Alex Smith, followed by Smith throwing a pair of touchdown passes&#8212;a 70-yarder to wide receiver Tyreek Hill and an 80-yarder to tight end Travis Kelce. The Broncos' only touchdown of the game was a 1-yard run by running back Justin Forsett, which occurred after a Justin Simmons' interception of Smith. A 52-yard field goal by placekicker Brandon McManus midway through the second quarter was the Broncos' only other scoring play of the game; a fake field goal attempt just before halftime was unsuccessful. After a scoreless third quarter, the Chiefs pulled away in the fourth quarter, with two field goals by placekicker Cairo Santos&#8212;from 27 and 39 yards out&#8212;and nose tackle Dontari Poe throwing a 1-yard touchdown pass to tight end Demetrius Harris (with a missed extra point). The latter field goal occurred after Broncos' return specialist Kalif Raymond muffed a punt return. With the loss, the Broncos were eliminated from playoff contention for the first time since 2010, lost all three of their AFC West divisional road games for the first time since 2010 and suffered their first season sweep at the hands of the Chiefs since 2000. The Broncos' streak of five consecutive playoff appearances&#8212;the longest in franchise history&#8212;came to an end. For the first time since 1966, the Broncos' offense scored 10 of fewer points for a third consecutive game. The Broncos' defense surrendered 330 yards in the first half&#8212;the most the Broncos have surrendered in a half since 1981, and 484 for the entire game&#8212;the most since 2013.
