> Conor McGregor tears ACL and meniscus at UFC 329, targets summer 2027 return

Conor McGregor’s long-awaited return lasted seconds. At UFC 329 on July 11 in Las Vegas — his first fight in five years, a rematch with Max Holloway — McGregor’s comeback ended by injury stoppage moments after the opening bell when his knee gave out on a jumping switch kick. On July 19, McGregor confirmed the damage: a torn ACL and meniscus, and a target of next summer to fight again.

A Familiar Injury, the Opposite Leg

The detail that stings for McGregor is the symmetry. As he described it, “It was ACL and meniscus. It is the same injury as the first Holloway fight, only this time the opposite leg.” McGregor and Holloway first met in 2013; that bout left McGregor with a knee injury that required surgery and kept him out roughly 11 months. He returned inside nine months to fight Diego Brandao back then — the precedent he’s leaning on now.

The Timeline

McGregor framed the recovery optimistically. “With today’s regenerative medicine advancements and improved training methods it is well within my realm to return by next summer,” he said, adding that he is already walking without a crutch and doing leg-extension work without issue. Applying the timeline from his 2013 recovery, a return around next June is plausible — though every McGregor timeline carries the caveat of his history of long layoffs.

Context: Five Years, Then Seconds

This is a brutal setback for a fighter who had already spent five years on the shelf following the leg break he suffered against Dustin Poirier in 2021. McGregor had lobbied to stay active in his comeback, even pushing for a December booking. That specific plan is now off the table, but McGregor struck a defiant tone: “On we go, no sad stories.”

For the UFC, the injury removes its biggest pay-per-view draw from the board for the better part of a year, reshaping the promotion’s marquee planning just as McGregor re-entered the picture.
