The pair first locked horns at UFC 178 back in 2014, with infamous Irish star McGregor walking away victorious with a TKO in under two minutes.
After a seven-year gap, the pair met once more at UFC 257 back in January, with Poirier this time turning out the victor. That leaves the pair tied at one win each going into this blockbuster deciding bout.
That's the main event, but the card's notional co-main event sees a welterweight head-to-head between Stephen “Wonderboy” Thompson faces #2 ranked Gilbert Burns. Both are looking to be considered for a title shot, so expect no ground to be given in The Octagon.
