ABU DHABI, United Arab Emirates (AP) — Dustin Poirier stopped Conor McGregor with a flurry of punches midway through the second round at UFC 257.
Poirier avenged his loss to the Irish superstar in 2014 with a knockout victory in their rematch.
Poirier caught McGregor with a series of shots to the head before buckling his knees with two left hands.
Poirier then sent McGregor to the canvas with a short right hand and finished it swiftly, setting off stunned excitement among the few thousand screaming fans allowed inside the Etihad Arena on Yas Island.
