The judges each scored it 49-46 in favor of Poirier.
Poirier snapped Holloway’s 13-fight win streak and ended Holloway’s bid to become the fourth double champion in UFC history. (Holloway is the current UFC featherweight champion.)
After 22 UFC bouts, the 30-year-old Poirier was fighting as a title challenger for the first time in his career. Only UFC Hall of Famer Michael Bisping had more fights in the UFC before his first UFC title shot.
Holloway and Poirier fought in 2012, with Poirier winning via a first-round armbar.
