Davis made his MMA debut in 2006, defeating Nick Wright in VFC 12. His thriving professional MMA career led to him retiring from a steady job as a wrestling coach in Pratt College and moving to the Quad Cities to train under Pat Miletich at his Mixed Martial School. He was ranked in the top 10 in the Featherweight division for World Extreme Cagefighting (WEC) and has also fought under Affliction, Titan Fighting Championships, Kansas City Fighting Alliance and other promotions.
In early Spring 2014, Davis signed with Bellator MMA, in the Bantamweight division. He debuted on March 21, 2014, beating Tory Bogguess via guillotine choke in the first round, bringing his record to an impressive 21 wins and just 6 losses.
