McGregor's return anchors a stacked UFC 329

UFC 329 fight week dominates the day out of Las Vegas, led by Conor McGregor's first walk to the Octagon in five years against Max Holloway. Beneath the headliner sits a genuinely deep card — a lightweight contender clash, an Olympic wrestler's debut, a former champ's weight-class jump — while matchmakers quietly stacked Shanghai, Sacramento and Noche UFC for the fall.

McGregor makes his return against Holloway atop UFC 329

Conor McGregor headlines UFC 329 on July 11 at T-Mobile Arena against Max Holloway in a welterweight rematch of their 2013 featherweight bout, marking McGregor's first fight since the leg break against Dustin Poirier at UFC 264 in July 2021. McGregor dismissed Holloway's stated plan to drag him into deep waters as disrespectful. The fighter class is split on the pick: Dricus du Plessis and Sean O'Malley back a McGregor knockout, while Sherdog's Sean Sheehan and others favor a fresher Holloway to finish the rusty Irishman at 170 pounds.

Why it matters: McGregor's five-year layoff at age 37 makes this the most scrutinized comeback in years, and a welterweight rematch against a durable, high-volume Holloway is a stern test of whether the sport's biggest draw still belongs.

Pimblett and Saint-Denis meet for lightweight position in co-main

Paddy Pimblett (23-4) faces Benoit Saint-Denis in the UFC 329 co-main event, a top-five lightweight bout in his first outing since losing an interim-title war to now-undisputed champ Justin Gaethje at UFC 324. Saint-Denis, riding four straight finishes including a 16-second KO of Beneil Dariush, dismissed fan concern over a foot scab as staph and insisted he is healthy. Pimblett wants his No. 5 ranking back and used the buildup to blast Arman Tsarukyan for chasing a title shot while wrestling in RAF instead of fighting in the Octagon, saying he 'beat an absolute bum' and needs to 'stop tickling people.'

Why it matters: The winner slots directly back into a Gaethje-headed title picture, and Pimblett's swipe at Tsarukyan crystallizes a real divisional debate: whether an inactive contender moonlighting in freestyle wrestling still deserves a lightweight shot.

Gable Steveson debuts as biggest betting favorite in UFC history

Olympic gold medalist and two-time NCAA heavyweight champion Gable Steveson (3-0, all first-round KOs) makes his UFC debut against Elisha Ellison on the UFC 329 prelims, opening as high as -4000 — described as the biggest favorite in promotional history. Steveson vowed to beat Ellison 'in the worst way possible' and credited coach Jon Jones, who has a one-third say in his camp at Jackson Wink. He also floated an eventual heavyweight collision with training partner Josh Hokit, whom he expects to drop to 205.

Why it matters: A wide-open heavyweight division badly needs new blood, and the UFC is betting heavily that an elite wrestling pedigree plus Jon Jones's tutelage can fast-track Steveson the way Hokit rose from the undercard to a White House main card.

Whittaker commits to light heavyweight, calls middleweight chapter closed

Former middleweight champion Robert Whittaker (26-9) debuts at 205 pounds against veteran Nikita Krylov on the UFC 329 prelims and says the move is permanent, calling the easier weight cut 'life-changing' after a rough two-fight skid to Reinier de Ridder and Khamzat Chimaev. Whittaker acknowledged the added danger — 'power is the ultimate equalizer' at 205 — but believes his skills are champion-level. Krylov, a natural light heavyweight, predicts the move flops like Israel Adesanya's and Chris Weidman's rather than following Alex Pereira's blueprint.

Why it matters: One of the division's most accomplished names is starting over at 205 at 35, joining a growing migration of ex-middleweights; how he fares against a rangy, durable spoiler sets the ceiling on his final run.

Sandhagen and Bautista run it back with title stakes

Cory Sandhagen and Mario Bautista rematch on the UFC 329 main card more than seven years after Sandhagen armbarred a one-week-notice Bautista in his 2019 debut. Bautista (17-3) is now a top-10 bantamweight who rebounded from a decision loss to Umar Nurmagomedov with a submission of Charles Oliveira, and predicts a finish; Sandhagen, coming off a close title-fight loss to Merab Dvalishvili, wants back in the conversation and expects to 'beat up Mario everywhere.'

Why it matters: With a Yan-Dvalishvili trilogy and a possible O'Malley rematch clogging the top of bantamweight, a clean win here gives either man a fresh, rematch-free case for the next title shot.

Garbrandt uses UFC 329 week to press promotion on fighter care

Former bantamweight champion Cody Garbrandt, 35, who faces Adrian Yanez on the UFC 329 prelims, called on the promotion to do more for fighters transitioning to retirement — pointing to the lack of healthcare, insurance and retirement plans for athletes classified as independent contractors. He cited Dustin Poirier, who retired last year and was recently arrested for alleged public drunkenness, defending him against media ridicule and saying many fighters struggle without the structure and income the sport provides.

Why it matters: Fighter pay and post-career support remain the sport's most persistent structural fault line, and a former champ raising it during the year's biggest fight week keeps the issue in front of fans and the promotion.

UFC Shanghai adds Yan Xiaonan vs. Gomes and more

The UFC booked Yan Xiaonan (19-5, 1 NC) against surging strawweight Denise Gomes (12-3) in the co-main event of UFC Shanghai on Aug. 29, with Umar Nurmagomedov vs. Song Yadong headlining. It's Yan's first fight in over a year following her decision loss to Virna Jandiroba, while Gomes rides a four-fight win streak. Also added: flyweight prospect Rei Tsuruya (11-1) against Kevin Borjas.

Why it matters: A win keeps the No. 5-ranked Yan in the 115-pound title mix, while Gomes has a chance to crack the contender tier — meaningful movement in a strawweight division still sorting itself behind champion Mackenzie Dern.
