Giving up: McGregor quits MMA- and UFC chief says it's for real this time
UFC chief Dana White believes Conor McGregor's latest retirement announcement is genuine and not a publicity stunt.
The Dubliner took to Twitter yesterday to announce that he had decided to call it a day.
He wrote: "I've decided to retire from the sport formally known as 'Mixed Martial Arts'.
"I wish all my old colleagues well going forward in competition."
McGregor (30) returned to the octagon last October after a hiatus of nearly two years but he was soundly beaten by Khabib Nurmagomedov.
The fight was marred by a post-fight brawl which led to both fighters being fined and suspended.
McGregor previously announced his retirement in 2016, only to return and fight again.
Following the latest announcement though, White says he believes this time is different.
"It totally makes sense. If I was him, I would retire too," White wrote.
"He's retiring from fighting, not from working. The whiskey will keep him busy, and I'm sure he has other things he's working on.
"He has been so fun to watch. He has accomplished incredible things in this sport."
Just hours before McGregor's announcement, he had appeared in a pre-recorded interview with TV host Jimmy Fallon in which he spoke about his intention to fight again.
