The Injury-Shortened Comeback
On July 11, 2026, Conor McGregor returned after a five-year hiatus to face Max Holloway in the main event of UFC 329 at the T-Mobile Arena in Las Vegas. Within 69 seconds, McGregor’s attempted jumping round-house kick caused his right knee to give way, leaving him unable to stay upright. Referee Mike Beltran stopped the bout, awarding Holloway a first-round TKO. The injury halted what had been billed as a $25 million gate-breaking showdown and marked McGregor’s third major leg injury in his career.
Recent Injury History & Contract Context
McGregor, 38, previously suffered a fractured left ankle in his July 2021 loss to Dustin Poirier and withdrew from a scheduled June 2024 return against Michael Chandler due to a broken toe. The UFC 329 loss occurred with one fight remaining on his current contract, after which he is expected to enter free agency. The timing of the injury raises questions about his ability to fulfill that final contractual bout.
Numbers Behind the Comeback
- Record before UFC 329: 22-7 (MMA), 10-5 (UFC).
- Holloway’s record entering the fight: 28-9 (MMA), 24-9 (UFC).
- Gate revenue for UFC 329: $25 million (record-breaking).
- Fight duration: 69 seconds (first-round stoppage).
Official Responses from UFC and McGregor
UFC President Dana White indicated that medical staff “assume it’s a blown ACL,” though a definitive diagnosis was pending. McGregor posted on Instagram that he will undergo surgery, followed by pre-hab and a return to martial-arts practice before his “final fight of the contract.” The promotion has not announced a timeline for his return, but the organization’s medical assessment suggests a potentially lengthy rehabilitation.
Skepticism from Holloway’s Camp
Ivan Flores, coach of Max Holloway, expressed doubt that McGregor will return at his previous level. He recalled his first impression of the incident: “When he threw the jumping kick, the first thing I thought of was, ‘Shoot, he lost his footing and slipped.’” Flores later added, “I don’t think so,” when asked about a possible McGregor comeback, noting that “if that knee is blown out… we’re looking at like another year.” His comments underscore concerns about the injury’s severity and its impact on McGregor’s confidence.
Conflicting Medical Assessments & Gaps
While UFC officials lean toward a torn anterior cruciate ligament, other analyses mention possible damage to the meniscus, MCL, or a combination of structures. No official imaging has been released, leaving the exact nature of the injury unconfirmed. Additionally, the timeline for surgical repair and rehabilitation remains unspecified, creating uncertainty about when—or if—McGregor can meet his contractual obligations.

What Lies Ahead
McGregor has confirmed that surgery is scheduled, but no date has been disclosed. UFC 329’s abrupt ending leaves the promotion without a marquee draw for the remainder of the year, and the organization has not indicated whether a rematch with Holloway or another opponent will be arranged once McGregor is cleared. The next public update is expected after his post-operative evaluation.
