Patrick Mahomes rallied the unbeaten Kansas City Chiefs back from a 10-point deficit in the fourth quarter for a 27-23 win over the Denver Broncos on Monday night.

The Chiefs (4-0) took a two-game lead over the Broncos (2-2) in the AFC West with their sixth straight win over their rivals.

Down 23-13, Mahomes directed a 12-play, 75-yard drive that ate up more than six minutes and culminated with a two-yard TD toss to tight end Travis Kelce, then added a 60-yard touchdown drive, handing off to Kareem Hunt for the four-yard score with 1:39 remaining. Mahomes has now thrown 14 touchdowns and zero interceptions in his first four games of the season.

It was the first time since 2004 that the Broncos blew a 10-point fourth-quarter lead at home. Denver abandoned its successful ground game in favor of three-wide receiver sets that resulted in a quick three-and-out in between Kansas City’s scoring drives.

Broncos quarterback Case Keenum had the chance to win the game in the final seconds but missed a wide open Demaryius Thomas, who would have been able to trot into the endzone.

Elsewhere on Monday, ESPN reported that Le’Veon Bell’s stand-off with the Pittsburgh Steelers will end when he returns to camp in Week 7, the team’s bye week. That would mean he could play for the Steelers again on 28 October against the Cleveland Browns.
