Colby Covington has become one of the most polarizing figures in mixed martial arts, his rise in notoriety coinciding with his emergence as one of the sport’s premier welterweights. The Clovis, California, native will celebrate his 30th birthday on Feb. 22.

Previous to his arriving on the MMA scene, Covington was an accomplished amateur wrestler. He won a national championship at Iowa Central Community College before becoming a two-time Pac-10 conference champion at Oregon State University, where he earned All-America honors in 2011. Operating out of the star-studded American Top Team camp, Covington made his professional MMA debut on Feb. 11, 2012 and won his first nine fights, three of them in the Ultimate Fighting Championship, before submitting to a Warlley Alves guillotine choke at UFC 194. He has since pieced together a five-fight winning streak, pushing his record inside the Octagon to 8-1. Covington last fought at UFC Fight Night 119 in October, when he claimed a unanimous decision from 2007 Abu Dhabi Combat Club Submission Wrestling World Championships gold medalist Demian Maia.

The aptly named “Chaos” has by design created plenty of enemies with his over-the-top trash talking, which included his referring to Brazilians as “filthy animals.” Prior to a UFC event in Sydney in November, Covington was involved in a highly publicized altercation with former heavyweight champion Fabricio Werdum, who hurled a boomerang at him. That resulted in his pressing assault charges against Werdum before going on bizarre public rants about fascism.
