Conor McGregor and Dustin Poirier have clashed against one another twice in the past, with both of them securing a victory over the other. Their first encounter at UFC 178 saw McGregor picking up a win by TKO, and Poirier repeated the same result at UFC 257 back in January this year.
Their UFC 275 encounter remains the last time they were seen in action inside the Octagon, as soon after the fight, both fighters agreed to a trilogy bout.
