Sean O'Haire - Mixed Martial Arts

Mixed Martial Arts

On October 21, 2006, O'Haire fought Eric "Butterbean" Esch at Pride 32 in Las Vegas. Esch was originally announced to be fighting Mark Hunt, but the Nevada State Athletic Commission would not allow Hunt to fight Esch arguing that Hunt had an unfair mat advantage. PRIDE had stated that "visa issues" were preventing Hunt from competing in the bout, but it was later confirmed that Hunt could not compete due to the Commission's ruling. The fight was stopped 29 seconds into the first round after Esch landed 4–5 straight punches to O'Haire's head to bring him to the ground.

On August 17, 2007, O'Haire was scheduled to fight Mark Kerr at the Mohegan Sun Arena for the Global Fighting Championships promotion but the entire card was canceled after four of the eight scheduled bouts fell through. No explanation was given at that time, regarding the cancellation, only a guarantee of a full refund. It was revealed by GFC representative Joel Parker that half of the night's fights were called off, prompting the decision to nix the card rather than put on a lackluster event. Parker did reveal that a few fighters were disqualified for either failing to meet their contracted weight or for medical reasons. Kerr and Edwin Dewees were pulled from the card by the overseeing athletic commission for missing weight. According to commission doctors, Kerr registered an unhealthy blood pressure reading the day prior. Kerr was set to fight O'Haire.

In 2007, O'Haire took part in Champions Quest Fighting Challenge. He was successful in his first fight on September 29, against Darrell Wood, and beat Frankie Parkman on December 7. However, he has not fought again as of December 2007. O' Haire defeated Tony Towers with a Guillotine Choke in the first round. O'Haire has had many MMA fights on smaller shows that are not listed by the major MMA fight databases.
