Conor McGregor’s UFC 329 return ends in 69 seconds due to leg injury

By Emily Turner — 13 July 2026 — 5 min read

Conor McGregor’s highly anticipated return to the UFC octagon at UFC 329 concluded in just 69 seconds after he sustained a leg injury during his fight against Max Holloway. The quick end to the bout has led to questions regarding the nature and timing of the injury, with McGregor himself stating he entered the fight without any pre-existing issues.

The fight saw McGregor attempt a series of jumping head kicks. On two occasions, he tumbled to the mat, and shortly after, he indicated he could not continue due to an injury to his right leg. This abrupt finish has sparked discussion among fans and commentators about what exactly transpired.

Injury Details and Speculation

Following the fight, UFC CEO Dana White suggested that McGregor might have torn the anterior cruciate ligament in his right knee. However, White also noted that this was speculation, as McGregor had not yet undergone a formal medical examination. White later shared a video of McGregor warming up backstage, showing him performing similar kicks without any apparent discomfort, which added to the confusion.

McGregor addressed the situation on social media, asserting that he had no injuries prior to the fight. He posted, “I was throwing kicks, planted and jumping, all throughout camp as well as backstage before the fight. This came out of nowhere.” This statement aimed to counter any theories of a pre-existing condition.

Joe Rogan, a commentator for the UFC, offered his perspective on the injury, describing McGregor’s initial kick attempt as a “crazy move.” Rogan explained that a jumping roundhouse kick, if not landed correctly, can place significant pressure on the knee, potentially leading to injury. He suggested that McGregor landed with his knee in a compromised position, possibly causing the ACL tear with his very first move.

Former MMA fighter and broadcaster Daniel Cormier also weighed in, suggesting that McGregor’s prolonged absence from the sport could have contributed to the incident. Cormier noted that fighters returning after a long break sometimes make decisions that do not make sense, attributing this to the intensity of being back in the octagon after a significant layoff.

The timing of an injury is a critical and sensitive matter in combat sports, particularly due to its potential impact on betting lines and the financial implications for an event. Disclosing a pre-existing injury could jeopardize the entire event, and promoters typically aim to ensure the integrity and unforeseen nature of the competition.

Fight Progression and Reactions

In the days leading up to UFC 329, McGregor showed no visible signs of concern about his legs. He was seen running onto the stage during a news conference and bouncing around at the ceremonial weigh-in, staring down Holloway. However, some observers noted a change in his expression as the fight approached.

Slow-motion footage from Paramount+, the official broadcast partner, showed McGregor looking down at his right leg while attempting to remove his shoe and then bouncing gingerly on his toes. While not definitive, this footage raised questions about any potential discomfort he might have been experiencing before entering the cage.

Once in the cage, McGregor performed his signature strut. However, Holloway later remarked that he immediately sensed something was amiss, stating that McGregor “didn’t seem like the same Conor.” Holloway also noted that McGregor appeared calmer than expected during the introductions by Bruce Buffer, lacking the pre-fight intensity he had displayed in the weeks leading up to the event.

The fight began with McGregor taking four steps forward and lunging at Holloway with a leaping left kick, landing awkwardly on his right foot. He stumbled, quickly recovered, and attempted another left head kick, which caused him to fall flat on his back as his right leg failed to stabilize. After another stumble, Holloway pointed to McGregor’s leg, and when McGregor clutched his knee in pain, referee Mike Beltran called off the fight.

Holloway recounted the moment, saying, “He grabbed his leg and screamed. I was telling the ref, ‘Come on, bro. What do you want me to do?’” He added that he was not interested in fighting an injured opponent. McGregor left the T-Mobile Arena immediately after the fight, declining to speak with media or commentators like Rogan. Videos later showed him walking with a limp.

UFC commentators Cormier and Rogan, along with former fighters Dominik Cruz, Chris Weidman, and Michael Bisping, all expressed the belief that the injury occurred during the fight itself. John Kavanagh, McGregor’s longtime coach, supported this view, stating on Facebook that the opening jump switch kick had been practiced daily without issue and that the knee gave out during the very first kick of the fight.

McGregor’s return was seen as an attempt to re-establish his UFC career, rather than for financial gain, given his past earnings. His previous fight was against Dustin Poirier on July 10, 2021. His current UFC career record stands at 22-7 following this TKO finish.

The Impact of the Injury

The incident has intensified the debate surrounding McGregor’s health and his standing as a prominent figure in the sport. The quick defeat and the nature of the injury have fueled various theories, including the possibility of fighters competing with undisclosed injuries, a scenario seen with TJ Dillashaw in 2022 and Manny Pacquiao in 2015.

McGregor’s previous leg injury occurred in 2021 during his fight against Dustin Poirier, where he broke his left leg. This latest injury to his right leg adds another chapter to his recent career challenges. His return was meant to redirect attention from a decade of turmoil, but it has instead generated new questions.

Despite the setback, McGregor maintained his shock and disbelief at the outcome. In a later post, he stated, “I was so sharp and so ready for this fight. I cannot believe what has happened. The talk of me being off while walking into the fight is nonsense. I was calm, ready, and confident. I am in shock what has taken place.” The wait continues for MRI results to provide clarity on the injury.
