Conor McGregor returns at UFC 257

Conor McGregor returns to the octagon for the first time in 12 months when he fights Dustin Poirier at UFC 257 on Abu Dhabi's Fight Island on Sunday.

The bout is a rematch of their 2014 encounter, which McGregor won via a first-round knockout, and will take place in front of a limited number of fans in line with coronavirus protocols.

The Irishman has not fought professionally since beating Donald 'Cowboy' Cerrone inside 40 seconds last January.

The 32-year-old McGregor has promised to "deliver a masterpiece", knowing victory could set up a potential mouth-watering rematch with bitter long-term rival Khabib Nurmagomedov.
