Former UFC champion Conor McGregor has announced on social media that he is retiring from Mixed Martial Arts.
McGregor is a former featherweight and lightweight UFC champion, and most recently fought Khabib Nurmagomedov in an event which smashed the company’s pay-per-view records.
“I wish all my old colleagues well going forward in competition,” McGregor said on Twitter. “I now join my former partners on this venture, already in retirement.”
