The American fighter Dustin Poirier knocked out the Irishman Conor McGregor in the UFC 257 in Abu Dhabi, United Arab Emirates.

"It's tough to be inactive for so long," said the 32-year-old Irishman, in what was only his third fight in over four years in the octagon.

Thrown to the ground from the beginning, where he doesn't feel comfortable, and then destabilized by Poirier's low kicks, "The Notorious" seemed to find his footing in the first round before collapsing in the second.

"His low kick to the calves was very good. Dustin is a true fighter," acknowledged McGregor, limping but sportsmanlike.

"It's hard to accept. I'm going to come back because it's what I've always done. I'm going to take this blow," he added.

Known for his legal troubles, his respectful behavior after his defeat is also perhaps a way of trying to forget his recent scandals: he was arrested for two days in Corsica in September following a complaint of attempted sexual assault and sexual exhibition. AFP
