Mixed martial arts career

Ultimate Fighting Championship

Steinbeiss was part of the transfer of light heavyweight and middleweight fighters in the WEC to the UFC. He was supposed to make his debut at UFC Fight Night 18 against Ryan Jensen, but the fight was pulled from the card. It was then rescheduled for UFC Fight Night: Diaz vs. Guillard. Steinbeiss lost the fight after Jensen applied a guillotine choke and the referee prematurely stopped the fight thinking Steve was out. Steinbeiss was instead giving the ref the thumbs up, the referee proclaimed that he thought Steinbeiss went limp. Steinbeiss was expected to face Nick Catone on January 11, 2010 at UFC Fight Night 20, but was pulled from the card before the event due to injury. Steinbeiss then faced Rob Kimmons on August 1, 2010 at UFC on Versus 2. Steinbeiss lost by unanimous decision to Kimmons and was released from the UFC.
