Conor McGregor has gone from an unknown plumber in Ireland to one of the most popular athletes in the world in about a decade. McGregor's skill in the Octagon and brash over the top personality rocketed him to the top of the Mixed Martial Arts world but that appears to be over. Just hours after saying he would fight in the UFC this July McGregor Tweeted out he's retiring from MMA.

Conor had some of the most exciting fights we've ever seen but really grabbed our attention with the microphone. If this is really the end for "The Notorious One" he walks away with a 21-4 record and championship belts in the UFC Featherweight and Lightweight divisions.

ESPN's Brett Okamoto asked UFC President Dana White if he thought the retirement was real via text. To which White replied "

"He has the money to retire, and his whiskey is KILLIN it, 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."

Conor McGregor's "Proper 12 Whiskey" is very popular and many insiders have asked if McGregor would still be motivated to fight now that he has that source of income.

This isn't the first time Conor has retired via Tweet. He Tweeted this in 2016.
