Floyd Mayweather thanks Dustin Poirier after huge win betting against Conor McGregor

The American boxer gambled a lofty sum of money against his former opponent, who he knocked out in 2017

Floyd Mayweather thanked Dustin Poirier for winning him $35,714.30 (£25,689.12) after defeating Conor McGregor.

The American emerged victorious after the Irishman suffered a gruesome leg injury at the end of the first round of their trilogy bout at UFC 264, with a doctor’s stoppage ending the contest despite McGregor making it to the end of the round.

The Irishman’s leg snapped, leaving him with just one win in the last four and a half years, and a lengthy road back to the Octagon.

But Mayweather, who knocked out McGregor in their 2017 super fight, revelled in the demise of his rival, wagering $50,000 (£35,964.76) on Poirier to win and pocketing the money despite the unexpected circumstances of the finish.

Mayweather tweeted his gratitude towards Poirier for helping to secure his windfall: “Dustin Poirier, thanks for getting me paid!”

With Poirier quickly responding: “I got you champ!”

After a disappointing end to the fight with McGregor’s hopes of redemption and revenge snatched away from him by the unfortunate injury, the animosity between the two fighters resurfaced.

But McGregor was in no mood to show respect to his American rival, instead taking aim at both Poirier and his wife.

“Your wife is in my DMs, hey baby,” McGregor snapped as his opponent returned to the dressing rooms.

“Hit me back up I’ll chat to you later on, I’ll be at the after party at the Wynn night club. You look in bits you little h**!

“I was boxing the ears off him, kicking the legs off him, usual s**** he dived to close the distance.”

“This is not over! If I have to take this outside with him it’s on outside I don’t give a b*******.”

Poirier looks likely to attempt to move on from McGregor and challenge Charles Oliveira for his lightweight title, but he could not resist a parting shot at the Irishman, labelling him “a dirt bag” following a bitter build-up to their third fight.

“I can take the trash talk,” Poirier told Joe Rogan. “There’s no holds barred with the trash talk, but murder is something you don’t clown around with, you don’t talk to people like that.

“He said he was going to send me home in a coffin, you don’t talk like that, I hope this guy gets home safe to his beautiful family.

“He hit me with a good cross , just like the last fight, I didn’t see it and it kind of clipped me, I was a little bit buzzed but my legs were still there.”
