Conor McGregor, the brash Irish mixed-martial arts fighter whose fame and showmanship transcended the sport he helped spread worldwide, said he was retiring in a message on Twitter today. After McGregor announced his retirement on social media, it was reported that the famous fighter was under investigation in Ireland after a woman accused him of sexual assaulting in a Dublin hotel last December. 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! I have decided to retire young. Thanks for the cheese. Catch ya’s later. That announcement turned out to not be true. If McGregor is truly retiring, he should have more than enough money. The UFC was a closed shop.
