McGregor suffered an excruciating defeat to a dominant Poirier after the Dubliner’s left ankle snapped at the end of the first round as he stepped backwards after throwing a punch.
The contest was called off as Poirier was declared the winner via a doctor stoppage TKO, putting the American 2-1 ahead in the trilogy between the two rivals.
Part of the build-up to Saturday night’s main event at the T-Mobile Arena had focused on McGregor’s return to his brash smack talk antics, including claims from ‘The Notorious’ that Poirier’s wife had attempted to slide into his direct messages on social media.
Poirier had shrugged off McGregor’s mind games, even claiming that the supposed Instagram request from wife Jolie to the Irishman could have been fabricated.
Poirier appeared equally unfazed on stepping inside the octagon, dominating much of the opening round before McGregor’s lower left leg snapped, bringing an end to the contest.
As McGregor sat in agony in the octagon he still continued to spit out barbs at Poirier and his wife.
WARNING: STRONG LANGUAGE
“This is not over,” a defiant McGregor fumed.
“If I have to take this outside with him it’s all outside. I don’t give a bollocks.”
“Your wife is in my DMs hey baby.
“Hit me back up we’ll catch you later on. We’ll be at the after party. The Wynn nightclub baby. You little h**. F*ck him.”
