Corey Hill

On May 14, 2015, it was reported that Hill had died after suffering from sudden pneumonia. According to friend Jennifer Swift, he had been diagnosed with pneumonia several weeks prior. It was reported that he underwent a lung transplant, but the lung collapsed. It was also reported that Hill was placed on life support until his family ultimately made the decision to remove him.

Hill died on May 15, 2015, at the age of 36, after suffering a collapsed lung and a heart attack.

Hill competed as a lightweight on The Ultimate Fighter 5 television series. During tryouts and production of the show, he told the UFC that his record was 10–0, but it was actually 2–0, both wins from amateur bouts. His first professional fight (albeit technically an exhibition) was on the show. It was scheduled against Gabe Ruediger, but he was expelled from the show for failure to make weight. Instead, Hill's match was against Rob Emerson and he won by a very controversial unanimous decision after three rounds. After defeating Emerson by decision in the preliminaries of TUF 5, Hill went on to lose in the quarterfinals by a triangle choke in the first round to fellow Team Pulver teammate, and future TUF 5 champion, Nate Diaz. Although he lost, Hill's performance validated the comments made several weeks prior by guest coach Jeremy Horn on Episode 3 of TUF 5, who suggested Hill had the potential to be a dominating force in the UFC Lightweight division—even going so far as to offer to train Hill after his run on the show.

On July 14, 2012, Hill defeated Darryl Madison at Complete Devastation 5 via anaconda choke submission.

On December 7, 2012, Hill lost to UFC & Bellator Vet Ryan Thomas at XFC 21: Night of Champions 2 via armbar submission.

In November 2011, Hill signed a long term multi-fight contract with XFC.

On December 2, 2011, Hill made his XFC Debut getting a first round submission win over Ultimate Fighter Alumni Charlie Rader at XFC 15: Tribute.

On January 23, 2010, Hill picked up a unanimous decision victory in his comeback fight against Jason Trzewieczynski just 13 months after his career threatening leg injury.

On March 20, 2010, Hill lost to Canadian Mark Holst via kimura submission at XKL: Evolution 1. On July 17, 2010, Hill defeated WEC Veteran Kit Cope at Raging Wolf 8: Cage Supremacy via triangle choke submission and on September 9, 2010, Hill lost to former WEC lightweight champion Rob McCullough at Tachi Palace Fights 6 via unanimous decision.

During the UFC: Fight for the Troops event in December 2008, Hill broke his right leg while throwing a kick that was checked by Dale Hartt in what is widely considered one of the most gruesome injuries in mixed martial arts history. Recovery from the injury was expected to take 12–18 months. With regard to organizational support, Hill told Kevin Iole of Yahoo! Sports: "The UFC was awesome throughout this whole thing and was so good to me, I feel indebted to them." His major sponsor, Fighter Warehouse, had paid a bonus and the XFC utilized an event which helped to raise money for the injured UFC fighter.
