Jason Douglas Black[1] (born August 15, 1972) is an American retired mixed martial artist. A professional from 2000 until 2007, he fought in the UFC, PRIDE Fighting Championships, King of the Cage, and the World Fighting Alliance.
Black was born in Ottumwa, Iowa and began wrestling when he was in the third grade. He moved to Bettendorf, Iowa and then began making the transition to mixed martial arts.
After a 3-0 amateur career at 185 lbs, Black turned professional in 2000.[2] He soon accumulated a record of 12-0 in small organizations such as SuperBrawl in Hawaii, Extreme Challenge, and HOOKnSHOOT with many of the wins coming in the first round. Black then fought future MFC Lightweight Champion Antonio McKee at World Fighting Alliance 1. The two fought to a draw.
Black continued his dominance, holding a record of 21-0-1 with wins over Ivan Menjivar, John Alessio, and Keith Wisniewski, before making his King of the Cage debut. Black fought against former WEC Welterweight Champion Shonie Carter and was given his first professional loss via TKO due to punches and to this date is the only TKO or KO loss of Black's career. Black then fought for Japan's PRIDE organization before being given a UFC contract.
Black made his debut with the Ultimate Fighting Championship at UFC Fight Night 10, losing to Thiago Tavares by triangle choke. He then lost at UFC 77 to Matt Grice by split decision after a very close fight that was originally ruled a draw when the score was incorrectly read. Black subsequently retired following the defeat.
Black is married and has two children.[3]
