UFC champion Conor McGregor has announced his retirement from the sport via social media.
In a Twitter post to his 7.5 million followers early this afternoon, McGregor said he was retiring from the sport ‘formally known as mixed martial art’.
The 30-year-old did not give any clue as to what he plans to do next.
McGregor is a former featherweight and lightweight UFC champion, and most recently fought Khabib Nurmagomedov in October, an event which smashed UFC’s pay-per-view records.
He retires with a record of 21 wins and four defeats.
However, the Irishman has only fought sparingly in recent years – the Nurmagomedov bout was his first in almost two years.
He is still suspended by the Nevada State Athletic Commission for his part in a brawl that broke out after that bout.
He famously also jumped in the boxing ring in 2017, losing to Floyd Mayweather Jr.
