UFC 257 will headline another notable matchup featuring the returning Conor McGregor going up against Dustin Poirier. The Irishman is returning to the lightweight division for the first time since 2018 while Poirier will look to avenge his 2014 loss to McGregor, this time as the No. 1 challenger.

Both fighters are expected to make a ton of cash as they vie to be one step closer to the lightweight title vacated by the recently retired champion in Khabib Nurmagomedov.

Via The Independent:

Poirier has a disclosed purse of $1million – already the biggest payday of his career – plus a share of the pay-per-view revenue. ‘The Diamond’s PPV share is not expected to be substantial, however.

McGregor, meanwhile, has a disclosed purse of $5m plus a share of the PPV. The Irishman’s share will no doubt be much greater than his opponent’s and it is thought that it could bolster his overall earnings for the fight to around $20m.

McGregor is coming off a disappointing loss to Nurmagomedov in the lightweight division back in 2018 which ended with a submission in the fourth round of the match. After the tough loss, he eventually decided to move up to the welterweight division and matched up against Donald Cerrone in UFC 246.

The 32-year-old McGregor looked like he was in peak shape as he came out with an impressive knockout victory in the first round of the bout. After improving to a 22-4-0 record, Conor McGregor then took almost a year off away from the octagon as he aimed to make a return to the lightweight division in 2021.

On the other hand, Dustin Poirier took advantage of McGregor's absence to ascend to the top of the division. He recently snagged a unanimous decision victory against Dan Hooker back in June of 2020 to improve to a 26-6-0, 1NC overall record and become the top contender in the division.

Both fighters will aim for a statement victory as they go head-to-head in Abu Dhabi, United Arab Emirates on Jan. 23.
