Denver's defense struggled to stop Chiefs running attack

The Denver Broncos opened the 2026 NFL season with a difficult night at Arrowhead Stadium, falling 31-10 to the Kansas City Chiefs on Monday Night Football.

Denver entered the AFC West showdown hoping to start the season with a statement, but Kansas City controlled much of the night behind a dominant rushing performance from Kenneth Walker III and a defense that never allowed the Broncos' offense to establish a consistent rhythm.

The loss drops Denver to 0-1, while Kansas City begins its season 1-0.
