Former Russian mixed martial arts star Khabib Nurmagomedov was removed from a Frontier Airlines flight following a dispute with crew. The UFC lightweight champion, who retired with a perfect 29-0 record, wrote in an X post on Monday that he resorted to flying with another airline after being deplaned. In a video widely circulated online, Nurmagomedov is seen sitting in the cabin's emergency exit row and talking to a crew member.
