Former UFC two-division champion Conor McGregor claims he’s retiring from MMA.

Out of nowhere early Tuesday morning, McGregor (21-4 MMA, 9-2 UFC) posted a message on his Twitter announcing that he’s done with “the sport formally known as mixed martial art” and wished his fellow fighters good luck in their future endeavors.

Hey guys quick announcement, I’ve decided to retire from the sport formally known as “Mixed Martial Art” today.

I wish all my old colleagues well going forward in competition.

I now join my former partners on this venture, already in retirement.

Proper Pina Coladas on me fellas! — Conor McGregor (@TheNotoriousMMA) March 26, 2019

Hey guys quick announcement, I’ve decided to retire from the sport formally known as “Mixed Martial Art” today.

Just hours after an interview aired on “The Tonight Show” with Jimmy Fallon in which McGregor claimed he was currently negotiating with the UFC about a July return to the octagon, “The Notorious” posted the message on social media. Whether it’s a true retirement or just a leverage tactic remains to be seen. A UFC official found the tweet to be “strange” in a text message to MMA Junkie.

UFC President Dana White apparently is taking McGregor’s words seriously.

“He has the money to retire, and his whiskey is KILLIN’ it,” White said in a statement obtained by MMA Junkie. “It totally makes sense. If I was him, I would retire too. 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. I am so happy for him, and I look forward to seeing him be as successful outside of the octagon as he was in it.”

McGregor famously announced he was hanging up his gloves with a “thanks for the cheese” tweet in 2016 when negotiations for a rematch with Nate Diaz at UFC 200 went sour, but he ultimately fought just over one month later at UFC 202.

Speaking with Barstool Sports’ “My Mom’s Basement” podcast Monday, White said it’s always a challenge to book a matchup with McGregor. This could be part of that.

“Every time I deal with Conor there’s always something,” White said. “There’s always something to deal with, and we get it figured out.”

McGregor’s six-month suspension for his role in the infamous UFC 229 brawl is set to be lifted April 6. Earlier this month, McGregor was arrested on strong-arm robbery charges in Miami for allegedly smashing and then stealing a fan’s phone outside a nightclub.
