McGregor to Return Against Holloway After Five Years

The announcement caps a turbulent stretch in McGregor's career. Long the sport's biggest star, he became the UFC's first simultaneous two-division champion after knocking out featherweight king José Aldo in 13 seconds in 2015 and beating Eddie Alvarez for the lightweight crown the following year. A lucrative 2017 boxing bout with Floyd Mayweather Jr. reportedly earned him tens of millions of dollars, but he has won only one of his four MMA (mixed martial arts) bouts since 2016. Off the cage, controversies have piled up: in October 2025 he accepted an 18-month doping ban for missing three sample collections by Combat Sports Anti-Doping, a suspension that expired in March, and an Irish jury in 2024 found him civilly liable in a rape claim brought by Nikita Hand, ordering him to pay £206,000 in damages.

For McGregor, the fight is part rematch — he outpointed Holloway at featherweight in 2013 — and part reckoning. Holloway, 34, has spent the decade since at lightweight's elite end, while McGregor, now 37, has not beaten a top opponent in 10 years, his sole victory coming against veteran Donald Cerrone in 2020. The question is no longer whether he can sell a fight, but whether years of injury, inactivity, and legal distraction have eroded the speed and timing that once made him a champion. With a reported $200 million fortune, he has little to gain financially; the real test is psychological — whether a fading star can rediscover the focus needed for elite combat. That answer will arrive on 11 July, five years and a day after the injury that paused his career.
