UFC 264's McGregor vs. Poirier is now live. Jennifer Maia slashed Jessica Eye's forehead and the shenanigans never stopped.

But when it comes to the main event, yesterday's weigh-in proved to be the final production for The Notorious One's return as he looks to break the tie record with his longtime rival. However, UFC head Dana White didn't give McGregor any chance to break things up after he tried to kick Poirier at the press conference. This is proof that McGregor can't wait. After their fight in January of this year, McGregor was knocked out in two rounds and lost, resulting in a 180-day doctor's stoppage. Six months later, McGregor is back to avenge that loss.

This fight was the third in a trilogy between the cocky Irishman and Dustin "The Diamond" Poirier, and if you think this one will also end in a TKO, you clearly have an eye for history. McGregor won by first-round TKO in their first meeting at UFC 178 in 2014.

Poirier could have followed up their last meeting with a fight for the lightweight title vacated by Khabib Nurmagomedov's retirement. Instead, he chose a big-money rubber match with McGregor.

There is a bit of drama in this match. On Tuesday, McGregor posted what appeared to be a screenshot of an Instagram DM request from Poirier's wife, Jolie Porter, on his Twitter account. This is probably fake, and there has been no official statement from Poirier about it yet. It seems best to ignore such shenanigans.

Poirier is the current favorite. Odds are as follows: Dustin Poirier (-130) vs. Conor McGregor (+110).
