The Most Heartbreaking Ending to the Biggest Comeback in UFC History: UFC 329

I don't know what to say about this one boys.

Conor McGregor sprinted across the canvas at the opening bell, launched a flying scissor kick at Max Holloway, and when he landed his right knee buckled. You could see it immediately. The leg wasn't right. He stumbled, he slipped to the canvas. Got back up and slipped again. Holloway looked at referee Mike Beltran and pointed at McGregor's leg, asking him to stop the fight. McGregor kept waving Holloway in, telling the ref he wanted to continue.

Then Holloway landed one calf kick, McGregor took an unsure step backward, and Beltran waved it off. 1:09 of round one. TKO by injury.

The most anticipated comeback in MMA history lasted 69 seconds.

History Repeating Itself in the Cruelest Way

In August 2013, McGregor fought Holloway for the first time at UFC Fight Night 26 in Boston. He won by unanimous decision. He also tore his ACL during the fight and fought the last two rounds on one leg.

In July 2021, McGregor fought Dustin Poirier for the third time at UFC 264. His left leg snapped at the end of round one. He sat on the canvas while Poirier stood over him.

In July 2026, McGregor fought Holloway for the second time at UFC 329 in Las Vegas. His right knee gave out in the opening seconds. Opposite leg from 2021. Same type of injury as 2013. Same opponent from 2013.

I'm not going to pretend that isn't devastating to watch. The man came back from a broken leg that took five years to recover from and his body broke again before the fight even got started. He threw one kick and his career potentially ended on impact. The mohawk he wore to the cage was the same style from his UFC debut over a decade ago. Like he was trying to channel the version of himself that started all of this. Like honestly dude this sucks.

Max Holloway's Class

What Max Holloway did inside that cage and after the stoppage is why he's the most respected fighter in the sport. Holloway repeatedly tried to get Beltran to stop the fight while McGregor was compromised.

"When we were in here, I was trying to call the fight off, and he kept asking to fight on," Holloway told the T-Mobile Arena crowd during his post-fight interview on the Paramount+ broadcast. "Let's give it up for Conor McGregor, guys. What an absolute animal."

The crowd was booing but not at Holloway, at the outcome. 20,000 people paid to see the biggest comeback in UFC history and instead watched a knee injury end it before a single real exchange happened. Holloway stood in the center of the cage asking a hostile crowd to show respect to the man he just technically beat.

Then he dropped the line that tells you he understood the moment perfectly.

"I had him weak in the knees, I guess," Holloway said to the Paramount+ broadcast team.

A joke. In the middle of the most awkward moment of the night. To lighten the mood because the crowd was furious and the fighter he just beat was limping out of the arena and nobody knew what to feel. That's Holloway man. Even when everything goes wrong he finds a way to make it human.

Then he asked for the trilogy. "There was so much hype. We'll run it back. We'll run it back one more time for the boys," Holloway said per Yahoo Sports.

Paddy Made It Look Easy

We wrote the preview on this fight. We said Paddy predicted BSD would try to wrestle and get submitted. We laid out the whole matchup. Paddy was right about everything.

52 seconds. BSD rushed forward into a wild exchange and immediately dove for a double leg takedown. The exact thing Paddy said would happen. Paddy sprawled, grabbed BSD's neck, and transitioned to a D'Arce choke. BSD went to sleep before the first minute of the fight was over.

"I said I was going to submit him and I submitted him," Pimblett told the Paramount+ broadcast team during his post-fight interview. The man called his shot and delivered in under a minute on the biggest stage of his career.

Paddy is now 22-4 with a first round submission on International Fight Week. BSD's four fight stoppage streak is over. And the co-main event that was supposed to be a war lasted less time than it takes to microwave popcorn.

The Rest of the Card Was Incredible

UFC.com E. Spencer Kyte wrote that "seven of the prelim bouts ended inside the distance" and the main card "offered more of the same with two more first round finishes and a pair of all action battles." The card was genuinely stacked from top to bottom and everything delivered except the main event.

Gable Steveson made his UFC debut against Elisha Ellison at heavyweight. The Olympic gold medalist we wrote the origin story on finally stepped into the Octagon after the wildest career path in combat sports. WWE flop. NFL cut. Back to college. And now the UFC.

Robert Whittaker made his light heavyweight debut against Nikita Krylov. The former middleweight champion who we wrote the origin story about finally stopped cutting 53 pounds and fought at his natural weight.

Cory Sandhagen fought Mario Bautista in a bantamweight bout that had title implications. Cody Garbrandt and Adrian Yanez threw hands. Brandon Royval fought Lone'er Kavanagh at flyweight. King Green and Terrance McKinney opened the main card.

The prelims were violent. The main card was stacked. The co-main ended in 52 seconds. And then the main event ended in heartbreak.

What This Means for McGregor

I'm going to keep this part short because we don't know the extent of the injury yet and speculating about a man's career ending while he's in a hospital getting scanned feels wrong.

Here's what we know. McGregor is 22-7. He turns 38 in three days. He hasn't won a fight since January 2020. He has one fight left on his UFC contract scheduled for April 2027. And his body has now failed him in three of his last four fights (the Poirier leg break in 2021, the broken toe that cancelled the Chandler fight in 2024, and now the knee).

The talent was never the question. Even at 37 with five years of rust, the McGregor who threw that flying kick at the opening bell was the McGregor who always shows up. Aggressive, fearless. Willing to put everything on one moment. That's who he's always been.

His body just won't let him be that person anymore.

Whether there's a trilogy with Holloway or whether this is the last time we see McGregor in the Octagon depends entirely on what the doctors say about that knee. If it's repairable and the recovery timeline is reasonable, the demand for McGregor vs Holloway 3 is massive. Holloway already asked for it. The UFC would book it tomorrow.

But if the knee is as bad as it looked on camera, the April 2027 date might come and go without McGregor ever stepping into the cage again. And the greatest career in MMA promotional history would end the same way it almost ended in 2021. On one leg in pain. Walking out without saying a word.

I hope he comes back bro I really do. But I'm not going to pretend that what happened last night didn't look like the end.
