Colby Covington fought at welterweight in the UFC.
Oregon is his birthplace. He trains at MMA Masters in Miami, and the pro debut was a knee-injury stoppage of Chris Ensley at 1:21 of the first round on February 11, 2012.
Iowa and Central Iowa Community College were his wrestling stops, he was a Pac-10 champion and a two-time NCAA All-American, and he earned a bachelor's degree in sociology from Oregon State. His mother gave him the nickname Chaos, from the first god in Greek mythology.
