Conor McGregor will be seeking redemption when he goes toe-to-toe with Dustin Poirier in the Octagon in an eagerly awaited trilogy fight at UFC 264 on Saturday night.
The pair clashed for the second time at UFC 257 on Yas Island, Abu Dhabi, back in January, with Poirier stunning McGregor and forcing a sensational stoppage in the second round.
And that victory would have tasted sweet for 'The Diamond', who was stopped inside the first round by McGregor during the duo's original featherweight bout at UFC 178 in September 2014.
McGregor, a former two-weight world champion, lamented his inactivity after suffering a third defeat in only his second UFC appearance since October 2018 - and he will want to set the record straight on Saturday evening.
The winner of this trilogy contest looks set to face new lightweight champion Charles Oliveira later this year after he beat Michael Chandler at UFC 262 in May to claim the belt that had been vacant since Khabib Nurmagomedov's retirement.
