Try as he might, Conor McGregor couldn’t quite outdo Bryce Mitchell on Friday. McGregor posted on social media to insult former opponent and fellow ex-UFC lightweight champion Khabib Nurmagomedov , his family and his culture. The post included multiple racial epithets for Black people. At this point in McGregor’s career, there isn’t much to say from a news standpoint. It’s merely the latest controversial post in a career filled with them.
