MMA fighter Conor McGregor has just announced that he is retiring from the sport.

In a tweet, the fighter wrote:

"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!"

The former UFC featherweight and lightweight champion returned to UFC last year after he took time away to make his boxing debut. The MMA star took on Floyd Mayweather but lost.

These days, McGregor has been making headlines for his behavior out of the ring. Most recently, he was arrested after he grabbed a fan's phone and destroyed it when the fan asked to take a picture.

He also received a suspension and fine earlier this year for a fight that broke out after an Oct. 6 fight in Las Vegas against UFC lightweight champion Khabib Nurmagomedov.

Fans may want to wait and see whether this retirement will stick. He retired once before back in 2016 but then hopped back into the ring.
