If you thought the UFC rivalry between Dustin Poirier and Conor McGregor was over, think again.

McGregor and Poirier fought three times in the UFC.

Their first meeting occurred in the featherweight division, way back in 2014. McGregor won that encounter by first-round TKO. It was an important victory for the Irish MMA superstar, as he had talked a ton of trash talk before the fight, and needed to back it up.

McGregor’s second meeting with Poirier occurred years later, in the lightweight division, in 2021. Unlike their first meeting, their wasn’t a ton of trash talk from either man in the lead-up. That ended up working well for McGregor, as Poirier ended up evening the score with a first-round TKO of his own.

After Poirier stopped McGregor in early 2021, they met for a third time to settle their 1-1 tie later that year. In the lead up to the trilogy fight, McGregor unleashed a ton of vicious trash talk, even targeting Poirier’s wife. In the end, he failed to back it up, as Poirier won by first-round TKO, and left his rival with a broken leg.

McGregor continued to talk trash in the immediate aftermath of his second loss to Poirier, but has not fought since, and has seemingly cooled off in the meantime. He even congratulated Poirier following the birth of his newest child.

McGregor’s message of congratulations prompted Ariel Helwani to ask Poirier about their rivalry during a recent interview.

Poirier made it abundantly clear he hasn’t forgiven McGregor for all the trash talk leading up to their third fight.

“F**k Conor,” he said.

When Helwani followed up for more information, Poirier only shook his head in clear disdain for the Irishman.

While McGregor would surely love to score another win over Poirier after this comment, he seems to have missed his chance. Poirier retired following a close decision loss to Max Holloway last summer.
