UFC Legend Dustin Poirier: I Lost My Mind. I’ll Never Let It Happen Again.

UFC legend Dustin Poirier reveals why he can't bring himself to watch the arrest video, the paid deals he's already lost, his vow to never drink again, and why the hardest fight of his life is happening off the mat.

Dustin Poirier (“The Diamond”) is a retired UFC lightweight fighter with a 30-10 record, best known as the only man to knock out Conor McGregor in MMA. He founded The Good Fight Foundation with his wife, Jolie, in 2018 and now appears periodically as a desk analyst on UFC broadcasts. In June 2026, he was arrested for public intoxication at an Atlanta airport, after which he shared that he’s struggling with alcohol. 

He explains:

◼ What losing your career identity feels like, and how to rebuild when the fight is over

◼ How a childhood of poverty, detention and no father figure shaped the man he became

◼ Why elite athletes often fall apart when they retire, and what to do about it

◼ What going to therapy taught him about the pain he didn't know he was carrying

◼ The mental shift that turned losing to Conor McGregor into beating him
