Jay Hieron height - How tall is Jay Hieron?

On March 7, 2014, Hieron announced his retirement from MMA competition.

Hieron was expected to face Erick Silva on February 2, 2013 at UFC 156. However, Silva pulled out of the bout citing an injury and was replaced by promotional newcomer Tyron Woodley. He lost the fight KO (punches) in round 1 and was subsequently released from the promotion.

Hieron was expected to face Jake Ellenberger in a rematch on September 1, 2012 at UFC 151, replacing an injured Josh Koscheck. However, after the UFC 151 event was cancelled, Ellenberger/Hieron took place on October 5, 2012 at UFC on FX 5. Hieron lost via unanimous decision.

Hieron faced Joe Riggs on January 30, 2010 at Strikeforce: Miami. Hieron won the fight via unanimous decision. After the fight had finished, Hieron's contract with Strikeforce was completed, prompting Hieron to immediately call for demands should he sign a new one. The demands included a shot at champion Nick Diaz and guaranteed television spots.

Following the demise of the International Fight League due to financial concerns, Hieron signed with Affliction in August 2008. However, that promotion soon folded as well, so Hieron signed with Strikeforce.

In March 2006, Hieron won the Lockdown in Paradise in Lahaina, Hawaii, and in June 2006 won his IFL debut at the IFL Team Championships in Atlantic City, New Jersey.

James Thomas Hieronymus (born July 29, 1976) is an American actor, stuntman and former mixed martial artist. Hieron was the final IFL Welterweight Champion, competing for the Los Angeles Anacondas, and has also competed in the UFC, WEC, Affliction, Strikeforce, and Bellator.
