Broncos vs. Chiefs Live Updates, Score: Who Will Win The AFC West Matchup?

Week 1 of the 2026 NFL season ends with a Monday Night Football battle between the last two AFC West champions, as the Denver Broncos travel to Arrowhead Stadium to take on the Kansas City Chiefs.

It's a pivotal night for both franchises. Denver dethroned Kansas City a year ago, snapping the Chiefs' nine-year run atop the division, and enters 2026 coming off a 14-3 record and the AFC's No. 1 seed. 

Kansas City is looking to bounce back from a 6-11 finish and its first missed playoffs since 2014 — a season derailed when Patrick Mahomes tore his ACL last December. Mahomes has been a full practice participant throughout camp and is expected to start, but how he performs in his return will be the storyline of the night.
