Conor McGregor is calling it a career (again).

On Saturday, right after Amanda Nunes’ big win over Felicia Spencer at UFC 250, McGregor took it to Twitter to announce his retirement.

“Hey guys I’ve decided to retire from fighting,” the 31-year-old MMA star wrote.

“Thank you all for the amazing memories! What a ride it’s been! Here is a picture of myself and my mother in Las Vegas post one of my World title wins! Pick the home of your dreams Mags I love you! Whatever you desire it’s yours,” he added along with a heart emoji and a photo with his mom.

It is unknown what triggered the Irish fighter to make the decision, but it sure was a surprise given that the UFC had an even in the same night.

Sure enough, it could also be a publicity stunt, as McGregor is known for his gimmicks off the Octagon. For what it's worth, in 2016, the so-called Notorious “decided to retire young” in 2016 amid negotiations about his next fight with UFC. Eventually, he resolved things with the organization and returned to fighting.

Moreover, in 2019, he made a retirement announcement for the second time. In his post, he cited he is leaving the “sport formally known as Mixed Martial Art.”

Given his history, it's not wrong to assume that McGregor is just trolling or perhaps he is using it as leverage in another fight negotiation.

However, if it is true and McGregor is truly ending his career, it is undoubtedly one of the biggest storylines of an already eventful 2020. He is also ending a largely dominant reign that saw him tally a 22-4-0 win-draw-loss record.

Conor McGregor last fought Donald “Cowboy” Cerrone last January 2020, a fight that saw him win in 40 seconds via knockout.
