False Start by Jaylon Moore Cost Chiefs Final Seconds Against Broncos

The Kansas City Chiefs lost their bid for a division lead to a procedural penalty that ended the game in the final seconds.

In Week 8 of the NFL season, the Denver Broncos defeated the Chiefs 28-24 at home. The deciding moment came on fourth-and-goal from the one-yard line with time expiring. A flag for a false start on Chiefs right tackle Jaylon Moore wiped out a touchdown pass from Patrick Mahomes to Rashee Rice. The play was originally ruled a score, which would have given Kansas City the win.

Because the penalty nullified the touchdown, the Chiefs had to replay the down. On the re-snap, Denver defensive end Jonathon Cooper and outside linebacker Nick Bonitto rushed the pocket. Linebacker Malcolm Roach sacked Mahomes, ending the drive and securing the victory for Denver. The result gave the Broncos a 6-2 record, placing them half a game ahead of the Chiefs, who dropped to 5-2.

Denver head coach Sean Payton credited the home crowd for the outcome. He noted that the noise level in the stadium contributed to the infraction by Moore. Payton recorded his 200th career NFL victory with the win. The Broncos have won 15 consecutive one-score games this season. Quarterback Russell Wilson, known for his clutch performance, recorded his 15th game-winning drive of the season.

Chiefs head coach Andy Reid disputed the call, describing it as one man's opinion. He stated that he saw Moore move his head but did not see the false start. Mahomes agreed with his coach, noting that such small infractions are rarely called in high-stakes moments. Despite the argument, Mahomes accepted the result, stating that teams must go with whatever is called.

The Chiefs' collapse began earlier in the fourth quarter with a separate penalty on Moore. With 13 minutes and 36 seconds remaining, Kansas City led 24-13. A pass to rookie running back Emmett Johnson was stopped short of the first down marker. The officials initially placed the ball two yards shy of the first down, prompting Denver to decline an illegal man downfield penalty. This set up a fourth-down situation and brought out the Chiefs' punt team.

Before the snap, officials re-spotted the ball less than a foot from the first-down marker. The change caught the coaching staff off guard. Reid did not call a timeout to reconsider the decision. Punter Matt Araiza kicked the ball through the end zone, giving Denver possession at their 20-yard line. Reid later admitted that keeping the offense on the field would have been a good decision if that had been the original spot.

Denver capitalized on the momentum. Quarterback Nix threw a two-yard touchdown pass to Nate Adkins with two minutes and 31 seconds left. He converted the two-point attempt with a pass to Jaylen Waddle, cutting the deficit to one point. The Chiefs failed to answer when kicker Harrison Butker missed a 54-yard field goal attempt. It was his fifth miss from 50-plus yards this season. The miss gave Denver the ball at their 44-yard line.

Rookie running back Jonah Coleman caught a 51-yard pass and ran it in for a touchdown to put Denver ahead. The Chiefs reached the Denver one-yard line with 15 seconds remaining. Denver's defense stood firm on the final play, aided by the earlier false start. Moore acknowledged the pain of the loss, noting that the close margin made the result hurt even more.
