Conor McGregor's Return Fight at UFC 329 Confirmed — The One Contract Detail

Conor McGregor is officially returning to the Octagon to face Max Holloway in the main event of UFC 329 on July 11, 2026, in Las Vegas, Nevada. UFC CEO Dana White announced the blockbuster rematch during the UFC Vegas 117 broadcast, locking in the former two-division champion to headline the promotion's annual International Fight Week card.  

While fans are celebrating the end of a five-year ring layoff, the sudden booking reveals a major structural shift in the UFC’s pay-per-view strategy. The long-anticipated fight with Michael Chandler has been completely abandoned, and McGregor’s decision to bypass his original lightweight plans signals a tactical move regarding his remaining contract obligations.

UFC 329 Main Event Ending Explained

The booking of Conor McGregor vs. Max Holloway 2 is a direct consequence of Michael Chandler's timeline expiring and Holloway's availability following his recent featherweight and lightweight runs. Because McGregor’s backdated Combat Sports Anti-Doping (CSAD) suspension officially expired in March 2026, the UFC needed a massive marquee attraction for International Fight Week to anchors its summer box office.  

Full Plot Breakdown: How the Chandler Fight Collapsed and Why Holloway is Next

The road to the UFC 329 main event is filled with broken bones, anti-doping red tape, and shifting corporate priorities. To understand why Max Holloway is standing across from the Irish superstar instead of Michael Chandler, you have to look at the timeline of the last two years.

The Cancelled June 2024 Return and the Broken Toe

McGregor and Michael Chandler were originally scheduled to square off in June 2024 after coaching against each other on The Ultimate Fighter. However, just weeks before the event, McGregor withdrew from the contest due to a fractured pinky toe sustained in training. The fight was indefinitely postponed, forcing Chandler to sit on the sidelines for over a year waiting for the biggest payday of his career.  

The Secret 18-Month CSAD Suspension

While fans expected the Chandler fight to be rebooked for late 2025, a massive hurdle emerged behind the scenes. McGregor accepted an 18-month suspension from Combat Sports Anti-Doping (CSAD) due to three "whereabouts failures" occurring when officials tried to collect biological samples.  

Because the suspension was backdated to late 2024, it quietly expired in March 2026. By the time McGregor was legally cleared to compete again, the promotional momentum for the Michael Chandler narrative had completely cooled off, prompting the UFC to look for a completely fresh, legacy-defining matchup.  

Enter the "BMF" Champion: Max Holloway 2

Instead of dragging out the Chandler saga, the UFC pulled the trigger on a 13-year rematch. McGregor and Holloway first fought all the way back in August 2013 at featherweight, where McGregor secured a unanimous decision victory despite tearing his ACL mid-fight.  

Holloway has since built a legendary Hall of Fame resume, including a dominant featherweight title reign and his iconic last-second knockout of Justin Gaethje at UFC 300. By booking the rematch at welterweight (170 lbs), the UFC allows both aging veterans to bypass a brutal weight cut, maximizing the chances that the fight actually materializes on July 11.  

Future Implications: What’s Next for Conor McGregor's Contract?

This fight marks a massive crossroads for McGregor's combat sports career. He has openly expressed his desire to fight out the remaining bouts on his active UFC contract to explore lucrative free-agency crossover fights, including highly publicized influencer boxing matches.

If McGregor defeats Holloway at UFC 329, he immediately inserts himself back into the global top-tier picture, setting up a massive potential title fight at 170 pounds. If Holloway exacts his revenge, it effectively ends McGregor's run as an elite title contender, transforming him strictly into a legacy attraction for the remainder of his historic career.
