Former UFC champion Dustin Poirier was arrested Sunday for public drunkenness, as first reported by TMZ.

The 32-fight veteran, who retired from the UFC in July 2025 and joined the broadcast team as an analyst, was arrested in Georgia on Father’s Day for what was listed as “public drunk,” which is a misdemeanor, at 6:38 p.m. ET.

It is unclear what led to his arrest, but he was released just after 10 p.m. ET.

“Love you all, I’m working on myself,” Poirier said in a post on his Instagram Stories after the news of his arrest dropped.

Poirier is married to his longtime wife, Jolie, and is the father of two children — Kingston, who was born in 2025, and 9-year-old Parker.

“Diamond” Poirier, 37, has been public about his tough upbringing, which saw him drop out of high school and work at McDonald’s in his early teenage years.

After finding martial arts and becoming a professional fighter, Poirier found his identity as one of the toughest combatants in UFC history.

He won the UFC Interim Lightweight championship in 2019 and finished with a career record of 30-10 (15 KOs).

During his last training camp at UFC 318, Poirier vowed not to drink alcohol and be sober for his final fight.

“Not that I didn’t check all those boxes in every other training camp, I just really, really focused on 90-something days completely sober,” Poirier noted. “No alcohol, no marijuana.”

Poirier wound up losing to Max Holloway by unanimous decision.

In an open and honest interview in January 2026, Poirier explained that alcohol had been a battle for him in retirement.

“I had retired and had so much time on my hands, and I’m always battling something in my mind,” Poirier told Ariel Helwani. “I’ve always drank alcohol growing up, but it was celebratory — vacation, get-togethers, things like that. Now I’m retired, and I’m sitting at home, and I can have a drink every day. I don’t have to wake up and run miles, I don’t have to wake up and go to the gym, or be somewhere. I just wanted to pull back from drinking.”

Poirier emphasized in January that he did not have an alcohol problem and had completed a 40-day sobriety challenge leading up to New Year’s this year.
