Conor McGregor walks to the octagon on July 11 for the first time since his tibia snapped on the T-Mobile Arena canvas at UFC 264. That was July 10, 2021. He is 22-6. His last three UFC results read: 40-second knockout of Donald Cerrone at UFC 246 in January 2020, KO loss to Dustin Poirier at UFC 257 in January 2021, TKO loss to Poirier at UFC 264 six months later. The Cerrone win is his last. Everything after it has been either a loss or an absence.
Across from him at UFC 329, Max Holloway (27-9), coming off a unanimous-decision loss of his BMF title to Charles Oliveira at UFC 326 on March 7. Holloway is moving up to welterweight for the rematch, which will be his first appearance at 170 pounds. The pair first met in August 2013 at featherweight, when McGregor took a unanimous decision from a 21-year-old Holloway at UFC Fight Night: Shogun vs. Sonnen. What was not known at the time was that McGregor tore his ACL during the fight, an injury he competed through and only had diagnosed afterward. Thirteen years on, the framing has inverted. Holloway is the busier fighter, the more recently competitive one, and the one who has actually held a belt this decade. McGregor is the draw.
That is the bout.
Sportsbooks agree on which way it should go. Holloway opened around -400 and has since floated between -240 and -300. McGregor is a +180 to +240 underdog, the longest underdog price of his UFC career. Prediction markets have Holloway near 67 percent and McGregor around 33 percent. That is not disrespect for either fighter. It is the market reading a 37-year-old returning from five years off, weighed against a 34-year-old with eleven fights against a murderer’s row over the same window that includes Alexander Volkanovski (twice), Poirier, Justin Gaethje, and Oliveira. Activity is not the same as advantage. It is not nothing.
The main event is contracted at welterweight, 170 pounds. McGregor has campaigned at that weight before, most notably in both Nate Diaz bouts in 2016 and in the Cerrone finish in 2020. Holloway is a career featherweight who moved up to lightweight permanently in 2024. Jumping straight to welterweight without a stopover, against a bigger natural opponent whose two wins at the weight both came inside the first round, is the storyline the trainers on both sides will be answering during fight week.
Five years is a long layoff by any measure. The last fighter to return from a comparable absence and win a headline bout in Las Vegas is a short list.
The co-main is Paddy Pimblett against Benoit Saint-Denis at lightweight. Pimblett is returning for the first time since his interim lightweight title loss to Justin Gaethje at UFC 324 in January, the first defeat of his UFC run. Saint-Denis is a French pressure fighter on a four-fight finish streak and the kind of test that tends to reveal what a prospect actually is. The winner is expected to slot into a lightweight title conversation now headed by newly crowned undisputed champion Gaethje after his upset of Ilia Topuria at UFC Freedom 250 on June 14.
Cory Sandhagen faces Mario Bautista at bantamweight in a top-ten fixture. Brandon Royval meets Lone’er Kavanagh at flyweight, another top-ten pairing. Robert Whittaker makes his light heavyweight debut against Nikita Krylov, moving up 20 pounds from the middleweight division he headlined for the better part of a decade. Whittaker’s move up is the subplot most likely to matter six months from now, depending on how the light heavyweight division sorts itself out. Krylov has been at 205 pounds his entire career and provides an immediate reality check on the size question.
Gable Steveson, the 2020 Olympic freestyle gold medalist at 125 kilograms, takes his first UFC walk against Elisha Ellison at heavyweight. Steveson signed with the promotion after a professional wrestling detour and has been training under Jon Jones. He is 3-0 in MMA with all three wins by first-round finish. The heavyweight division has been waiting on him for a while.
Former bantamweight champion Cody Garbrandt faces Adrian Yanez on the main card. King Green meets Terrance McKinney at lightweight. Alessandro Costa steps in against Cody Durden on the prelims after Ode Osbourne withdrew injured earlier this week, with Costa fighting for the second time in just over a month after his TKO of Matt Schnell at UFC Vegas 118 in early June. The Farid Basharat vs. Ethyn Ewing prelim has been pulled from the card in a separate shuffle, with the current status of that slot still being finalised.
UFC 329 streams on Paramount+ in the United States, with no pay-per-view attached, part of the promotion’s rollout of the $7.7 billion Paramount deal that took effect earlier this year. Early prelims begin at 5 p.m. ET, main card at 9 p.m. ET, McGregor and Holloway expected around 11 p.m. ET. Weigh-ins are Friday.
International Fight Week traditionally leans on a marquee return or a title fight. This year the UFC has both a return and a rematch of a fight almost no one under 25 remembers watching live. The gate at T-Mobile and the eventual viewership numbers will tell the commercial story soon enough. The UFC has not publicly disclosed either figure at time of writing.
What happens inside the cage is the harder read. McGregor has fought once since 2020. Holloway has fought eleven times. The sportsbooks think that difference is decisive. Nine days out, the card is intact enough, the main event is still the main event, and the sport is about to find out whether five years off has left anything of Ireland’s biggest export to combat sports.
