Conor McGregor is 37, and that number matters now because the comeback is no longer a theory, a tease or a social-media fantasy. On Saturday night in Las Vegas, he is set to return against Max Holloway in the UFC after a five-year absence, and that is exactly the sort of fact pattern that forces a hard question: what does McGregor still have left to give?
The obvious answer is that he still has star power in abundance. McGregor does not need an introduction, a soft landing or a reminder of what he once was. He made history as the first fighter to hold two world titles across different weight divisions at the same time, and his defining nights against Jose Aldo, Khabib Nurmagomedov and Nate Diaz helped shape an entire era. That is the burden and the appeal of a return like this. He is not just another veteran coming back after time away. He is one of the most recognisable fighters the sport has ever produced.
A comeback with real questions attached
But age, in fighting, is never just a number. It is context. McGregor’s last UFC appearance came after the broken leg he suffered in his trilogy bout with Dustin Poirier in 2021, and this return has not come smoothly. A planned comeback in 2024 was scuppered by a toe injury, while his 18-month doping suspension only ended in March. That is a long stack of interruptions for any athlete, let alone one trying to re-enter one of the most punishing sports on the planet.
That is why this return feels bigger than a routine booking. It is a test of whether McGregor can still turn his name into performance, not just headlines. The sport has moved on in his absence, even if he has remained impossible to ignore. There was the 2017 boxing match with Floyd Mayweather, one of the most profitable single-day sporting spectacles in history, and there have been the business ventures too, from Bare Knuckle Fighting Championship to Forged Irish Stout and an appearance in Amazon Prime's reboot of Road House.
His public life has also kept drifting into the kind of territory only McGregor could make feel halfway plausible. In 2021 he posted that he was thinking about buying Manchester United after the European Super League's collapse, later saying, "Hey guys, I'm thinking about buying Manchester United! What do you think?" and, "Both Celtic and Manchester United are teams I definitely like. I'm open, I feel like I could do great things for a club." Then in March 2025 he formally announced a campaign to stand for President of Ireland. That is the scale of the profile we are dealing with: combat sports icon, celebrity entrepreneur, political attention-grabber, permanent headline generator.
The problem is that none of that changes the central sporting question. At 37, after five years away, after injuries and suspension and all the noise that follows him everywhere, McGregor is no longer being judged on promise. He is being judged on whether the return still looks like the beginning of something or simply the latest reminder of what once was. Against Max Holloway in Las Vegas, that answer is about to get a lot clearer.
