In a surprising turn for the mixed martial arts world, UFC legend Dustin Poirier is set to retire from the sport after his highly anticipated main event bout against Max Holloway at UFC 318 this Saturday. Despite being 36 and still considered among the top lightweight contenders, Poirier’s decision to hang up his gloves comes down to deeply personal reasons: his family and long-term brain health. This retirement marks the end of an illustrious career for one of the UFC’s most dangerous fighters and a true fan favorite.

The Retirement of a UFC Legend: Dustin Poirier’s Final Fight
Make no mistake about it: Dustin Poirier is still at the top of his game. Even at 36, he remains among the UFC’s most dangerous fighters both standing and on the mat. He has notable wins over Conor McGregor, Michael Chandler, and Benoît Saint Denis in recent years. So why, despite a No. 6 ranking among lightweights and a headlining fight at UFC 318 against Max Holloway in New Orleans this Saturday, does he plan on taking off the gloves for good?
It all comes down to family. “Me and my wife have been together for a long time, since before I was fighting, so she’s been on this whole journey with me,” Poirier told NBC News last week. “She’s been asking me to stop fighting for a long time, and so has my daughter.”
After 30 wins in 40 fights, a resume mostly made up of all-out wars that have made him a fan favorite, the Lafayette, Louisiana, native has followed their advice. He will walk out in front of his hometown crowd and compete for the final time, ending a legendary career as a UFC legend. Poirier’s decision to prioritize being there for his family for the long run, both physically and mentally, reflects a growing awareness of the sport’s long-term toll.
Prioritizing Brain Health: A Major Factor for UFC Fighters
Poirier explicitly stated that his long-term health was a major factor in his decision. “I want to be there for my family for the long run,” he said. “I want to watch my daughter get married and always be there for her, not just physically, but mentally, too. I want to leave with my faculties. This isn’t good for you. Getting kicked and kneed and punched in the head for 18 years isn’t good for you.”
He officially came to terms with the decision after his last fight against Islam Makhachev in June 2024, where he suffered his third championship defeat. Recognizing the wear and tear on his body since he began fighting at 17, a long winning streak to get back into title contention seemed unlikely at his age. This highlights a crucial point for all UFC fighters: the impact of repeated head trauma.
Max Holloway and the Importance of Brain Health
Dustin Poirier’s opponent at UFC 318, Max Holloway, has also been outspoken on the topic of brain health. Before his UFC 308 title fight against Ilia Topuria in October 2024, Holloway emphasized: “You only get one brain. Once that thing starts deteriorating, it’s not like anything else where you can grow it back. Be smart, go see specialists, go see doctors, go do research on your own brain health and take care of yourself. At the end of the day, that’s what it is. I don’t want to be a vegetable when I grow older.”
UFC’s Efforts to Protect Fighters’ Brain Health
The UFC has taken significant steps to help athletes protect their brains and mitigate the risks associated with repetitive head trauma, a critical concern for UFC fighters.
- Concussion Protocol: According to the promotion, a five-stage protocol is used to determine if a fighter is fit to return to action after a concussion.
- Post-Bout Examinations: Every fighter undergoes an immediate full examination by a commission doctor and a UFC physician after their bout. They may be required to undergo a CT brain scan, an MRI brain scan, and/or have a neurology follow-up evaluation.
- Cleveland Clinic’s Professional Athletes Brain Health Study: The UFC has contributed more than $2 million to this ongoing study. Since 2011, over 900 athletes have participated in testing to determine the long-term effects of repetitive head trauma and factors that put certain individuals at higher risk of developing Chronic Traumatic Encephalopathy (CTE). Dr. Charles Bernick, the founder and primary investigator, highlighted the goal of empowering athletes with knowledge about their brain health.
While no study has been completed solely focused on MMA or boxing fighters, research on former NFL players, such as Boston University’s CTE Center announcing that 91% of 376 former football players studied were diagnosed with CTE, underscores the seriousness of head trauma in contact sports.
The Perfect Exit for a UFC Fan Favorite
Facing Max Holloway this Saturday for the UFC’s “BMF” belt — a title distinguishing the promotion’s “Baddest Motherf—-r” — is a nice consolation prize for years of thrilling fights for Dustin Poirier. He could walk out to the octagon in front of his hometown crowd, beat another fan favorite, and leave with gold around his waist. It would be the perfect ending to one of the UFC’s most storied careers. Poirier emphasized how important it was to get out of the sport before the sport got him out, avoiding the fate of many fighters who competed past their prime and suffered life-altering damage.
“I’m not getting forced out of this,” he said. “I’m choosing to walk away, and that’s very important to me.” This sentiment resonates deeply, highlighting his agency in his retirement. His journey, from his early days to becoming a UFC legend, has been truly remarkable.
