Conor McGregor steroid allegations: team fires back

Conor McGregor has not even made the walk yet, and UFC 329 is already being fought in depositions of public opinion.

The comeback was supposed to be simple enough to sell: McGregor back under the lights, Max Holloway across from him, old history dragged into a modern main event. Instead, fight week has been swallowed by a dispute over banned-substance claims, a newspaper investigation, and a management team that clearly believes the timing is no accident.

Audie Attar, McGregor’s longtime representative, pushed back on The New York Times after its reporting linked the Irish star to alleged steroid and HGH use during his recovery from the broken leg suffered against Dustin Poirier. Attar’s line is straightforward: the procedures were followed, McGregor has been tested heavily in 2026, and the story arrived at exactly the sort of moment guaranteed to cause maximum damage.

Conor McGregor steroid allegations shadow UFC 329 return

McGregor’s absence from competition began with one of the ugliest endings of his career. The Poirier trilogy at UFC 264 closed with McGregor on the canvas after breaking both the tibia and fibula in his left leg, a scene that turned a rivalry fight into a long medical and professional reset. Since then, every photo, delay and cancelled comeback has been treated as evidence by somebody, even when it proved nothing by itself.

The New York Times reporting, as relayed by BJPenn.com, centers on claims that McGregor used prohibited drugs after surgery while rebuilding from that injury. The article also says there is no direct proof currently showing that McGregor used steroids or other banned substances before UFC 329. That is not a small caveat. In a sport where reputations can be dented by suspicion alone, the gap between allegation and documented violation still matters.

Audie Attar challenges the accusation and the calendar

On The Ariel Helwani Show, Attar argued that McGregor has been through roughly 15 tests this year and insisted the camp has met the anti-doping requirements placed in front of it. He described the Times piece as a “hit job” and suggested the publication date was meaningful, arriving near both a major UFC White House moment and McGregor’s scheduled return against Holloway. Attar also welcomed public support from Hunter Campbell and the UFC, a sign the promotion is not treating this as routine background noise.

• McGregor is booked opposite Max Holloway in the UFC 329 headliner this Saturday.
• His most recent UFC appearance was the 2021 loss to Dustin Poirier at UFC 264.
• The disputed report alleges steroid and HGH use during McGregor’s post-surgery rebuild.
• BJPenn.com states that direct proof of banned-drug use before UFC 329 has not been shown.

McGregor vs Holloway 2 becomes a pressure test for everyone

The sporting angle is still enormous, even if the controversy is louder right now. McGregor defeated Holloway in 2013, before either man became what he is today: McGregor the UFC’s most famous crossover attraction and a former simultaneous two-division champion, Holloway a former featherweight titleholder with one of the deepest résumés of his era. Their rematch is not just nostalgia. It is a measurement of what McGregor has left and whether Holloway can turn another man’s circus into his own statement win.

The stakes stretch beyond the two names on the poster. If McGregor wins, scrutiny will follow the performance and the UFC will have to live with the debate while enjoying the business. If Holloway wins, he cuts through five years of McGregor mystery with one clean result and strengthens his own position for whatever major fight comes next. For the division and the promotion, the cleanest outcome would be a fight that produces clarity, though McGregor events rarely offer much of that.

There is a fair way to look at this without turning into either a defense lawyer or a mob. McGregor’s camp can demand facts rather than insinuation, and fans can still ask hard questions about a five-year gap around the sport’s most scrutinized star. The only confirmed competitive piece, for now, is that Conor McGregor is scheduled to fight Max Holloway at UFC 329 this Saturday.
