Darren Erdley Stewart (born 30 December 1990) is a retired English mixed martial artist. A professional competitor since 2013, he competed in the Middleweight division of the Ultimate Fighting Championship and Cage Warriors.

Background

Stewart was born in Poplar, East London, England. His father was from Jamaica and his mother was from St Vincent. Encouraged by his mum, Stewart started MMA training at 13 for self-defence due to the crime rate was high in London with the youth during that time. His friend Regan Lawrence was at The MMA Clinic at that time and invited him to try on MMA, even though his initial thought was "I’m not doing that crap, cage fighting. I’ve seen the blood on TV. No way", but he eventually found MMA full contact striking exciting, and thrived where he competed in the UK and abroad.

Stewart worked as a full-time prison officer for the Crown Court in London Bridge.

Mixed martial arts career

Early career

Stewart fought most of the fights in England and picked up seven consecutive wins with five by knockout before signed by UFC. He was the former Killacam light heavy weight champion in England.

Ultimate Fighting Championship

Light heavyweight

Stewart made his promotional debut on 17 September 2016, at UFC Fight Night: Bader vs. Nogueira 2 against Francimar Barroso at São Paulo, Brazil. Stewart was initially declared the winner of the fight via TKO, but the decision was overturned by Comissao Atletica Brasileira de MMA (CABMMA), after an appeal from Borroso, as a result from an accidental head butt prior Stewart rained down a series of heavy punches. The bout was finally declared as no contest. Calling for a rematch when UFC would return to London, Stewart was displeased with the CABMMA decision and commented "The entire situation stinks. I put a lot of time and money into this fight, won the fight, and his mates at the Brazilian MMA Commission overturned the decision. Fighting a Brazilian in Brazil is something that every fighter should think very strongly about. Had I lost and made an appeal to the Brazil commission, I doubt it would be overturned because I’m not from Brazil.”

The match with Francimar Barroso was rescheduled on 18 March 2017, at UFC Fight Night: Manuwa vs. Anderson. He lost the fight via unanimous decision.
