Mahomes' Meltdown: Chiefs Suffer Stunning Collapse Against Jaguars

The Kansas City Chiefs let a 14-0 lead slip away in Jacksonville on October 6, 2025, losing 31-28 to the Jaguars on Monday Night Football and falling to 2-3 in a season that would become the worst of the Patrick Mahomes era.

Kansas City scored on its first two possessions, a 2-yard Mahomes pass to Travis Kelce and a 9-yard Mahomes run, then watched Jacksonville answer with 21 straight points. The Jaguars’ official game report confirms the 31-28 final, and the box score tells the story of a team that won most of the stat sheet and still lost: Kansas City outgained Jacksonville 476 yards to 319 but was flagged 13 times for 109 yards, according to ESPN’s game page.

The Turning Point: Devin Lloyd’s 99-Yard Pick-Six

The game swung late in the third quarter. With the score tied 14-14, the Chiefs had second-and-goal at the Jacksonville 3 when Mahomes threw a short pass toward JuJu Smith-Schuster. Linebacker Devin Lloyd stepped in front of it at the 1 and ran it back 99 yards for a touchdown, shown in the Jaguars’ official highlight. That one snap was a 14-point swing. Instead of a likely 21-14 Chiefs lead, Jacksonville went up 21-14 with 2:19 left in the third. NFL Research called it the longest defensive score in Jaguars history and the longest regular-season pick-six by a linebacker in NFL history. Mahomes said afterward that Jacksonville had shown him a look it hadn’t used on film. He checked into in-breaking routes expecting the defenders to pass receivers off, and, as he told CBS Sports, the linebackers “popped right underneath with where I was going to throw the ball.” He also put the loss in context of a bigger pattern: “We’ve executed at certain points in the game and looked really good and then we kind of crush ourselves with penalties and mistakes and interceptions and fumbles or whatever that is,” Mahomes said, per FOX Sports. “It’s just — we’ve kind of done that to ourselves all year long.”

The Late Lead That Didn’t Hold

The Chiefs came back. Trent McDuffie intercepted Trevor Lawrence early in the fourth, and Kareem Hunt scored from 5 yards out to tie it 21-21. After a 52-yard Cam Little field goal put Jacksonville back up, Mahomes led a 12-play, 86-yard drive that ended with Hunt’s second touchdown of the quarter, a 2-yard run for a 28-24 lead with 1:45 left. The defense couldn’t close. Lawrence hit Brian Thomas Jr. for 33 yards on the final drive, and a Chiefs interception in the end zone was wiped out by a flag. Defensive pass interference on Chamarri Conner gave Jacksonville the ball at the 1. The winning play almost didn’t happen. Lawrence got stepped on by his own guard, fell at the snap, got up, and ran it in with 23 seconds left. ESPN’s recap described the score as a “comical miscue” turned into an improbable touchdown. Lawrence, playing on his 26th birthday, ran for two touchdowns and threw for one. The loss ended a 22-game winning streak for Kansas City in games where it led by 14 or more. Before that night, the Chiefs were 62-4 with Mahomes at quarterback when leading by at least 14, according to FOX Sports.

‘We’ve Lost Too Many Games Already’

Mahomes kept his postgame message short. “We got to do better,” he said. “We’ve lost too many games already. We got to find a way to be better.” His own numbers were good: 29 of 41 for 318 yards, one touchdown pass, one interception, and a rushing score, per Sports Illustrated’s Arrowhead Report. The real problem was the flags. The 13 penalties and 109 penalty yards were Kansas City’s most since its 54-51 loss to the Rams in November 2018, and 10 of the flags came after halftime. Andy Reid didn’t argue the calls. “You have that many penalties, you give up field position, you can out-stat them to death, but it doesn’t matter,” he said. “It’s the score that matters.”

This was Kansas City’s third one-score loss in five games. For a team used to winning close games, that kind of record was a warning sign. Follow the rest of the season in Double Hype’s NFL coverage.

We now know how it ended. The Chiefs finished 6-11, missed the playoffs for the first time since 2014, and had their first losing season since 2012. Mahomes tore his ACL in a Week 15 loss to the Chargers, the same game that eliminated Kansas City, according to ESPN. Seen from there, Jacksonville wasn’t just one bad night. Blown leads, penalties, and losses decided by a single score kept showing up all season.

What the Jacksonville Loss Revealed

The talent was there. Kansas City still had Mahomes, Reid, and a roster that had reached seven straight AFC Championship Games. But the Jacksonville game showed problems a great quarterback couldn’t cover up.

Special teams hurt them badly. CBS Sports counted four special-teams penalties, including one on the final kickoff return that cost the Chiefs field position they needed for a possible tying field goal.

The defense let several chances slip. Sports Illustrated noted that a Jaguars deep ball bounced off a Chiefs defender’s hands and a would-be Nick Bolton interception was knocked loose when teammate Drue Tranquill ran into him, keeping alive a drive that ended in Jacksonville’s first touchdown.

Travis Kelce summed up the frustration on the “New Heights” podcast, pointing to the 14-point lead and the penalty count as the difference.

The discussion afterward came down to one question: were these fixable, week-to-week mistakes, or signs of a roster too thin to survive its own errors? The rest of the season answered it.

The penalties weren’t a one-week problem. FOX Sports said the 13 flags were the team’s most since 2019 and the 109 yards the most since 2018, during a stretch of three straight one-score losses.

This 2025 team had more cracks than any earlier version of the Mahomes-era Chiefs. Mahomes could still produce big numbers, as his 318 yards showed, but the team around him kept giving games away.

Offensive mistakes, coverage breakdowns, and special-teams flags all showed up in the same game. That’s how a team can outgain its opponent by 157 yards and still lose.

For Jacksonville, the win was a statement. The Jaguars moved to 4-1, their first such start since 2007, according to NFL.com. Lloyd, the AFC Defensive Player of the Month for September, made the biggest play, and Lawrence made the plays he needed on the final drive.
