​Conor McGregor is back in the UFC, but how long will it last? Win or lose against Max Holloway this weekend, the Irishman may still face challenges that loom larger than the outcome of a single fight. It wouldn’t be his first hurdle. The five years since his last Octagon appearance have been punctuated by a broken leg, a broken toe, a canceled event, a failed bid for the Irish presidency, missed drug tests, a driving ban, a sexual-assault allegation, and a rape trial.
McGregor has denied the sexual-assault accusation, which did not lead to criminal charges, and the plaintiff in a related civil case ultimately dismissed the claim with prejudice. As for the rape trial, a civil jury found him liable, though he again denied the allegations and appealed the verdict, without success. Now, three days before his UFC comeback, he has leaned heavily on his faith in public life, while also showing signs of agitation.
Some of that tension can be attributed to the sheer desire to return to competition. He will be stepping back into the same arena—the T-Mobile Arena in Las Vegas—where he fractured his leg in the 2021 loss to Dustin Poirier. It is the same venue that hosted UFC 303 in 2024, shortly after McGregor was forced out of the event by a broken toe.
Given all these chapters, McGregor will not feel settled until he is actually inside the cage with Holloway. And those who can’t wait to see him fight—an immense and devoted following—will not be satisfied until they witness him in action. Regardless of any personal opinions about McGregor, the blunt truth is that MMA has rarely experienced a fight week like a McGregor week. The mainstream attention he once commanded continues to echo from the mid-2010s, a period when he brought the sport into a broader spotlight as a fighting phenomenon.
That era included a string of remarkably precise predictions and knockout wins against elite opponents (the so‑called “Mystic Mac” phase), followed by two title wins across different weight classes, his dramatic revenge against Nate Diaz, and a monumental boxing bout with Floyd Mayweather Jr. After that peak, his in-ring appearances dwindled. He openly acknowledged a combustible relationship with alcohol and even launched his own whiskey brand, though that business would later distance itself from him amid the ongoing legal proceedings.
So, by 2021 it felt almost surreal to see McGregor back in the Octagon, again twice in six months. Both bouts against Poirier ended in defeat—his first-ever knockout loss preceded by the leg break that will be recalled in the memory of this week’s matchup. Now, the gap between his last fight with Poirier and this weekend’s clash with Holloway exceeds anything he has previously endured.
Against Holloway, he is facing a familiar adversary in an old rival: a challenger he once outpointed thirteen years ago, a man who has since grown into a seasoned contender, one who has earned a place among the sport’s most intimidating figures. This is not just a reunion with a former opponent; it is a confrontation with the evolution of both fighters and the enduring question of how long McGregor, in his current form, can stay at the pinnacle of a sport that has moved on in his absence.
