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.
