“Big” John McCarthy is the most famous referee in MMA, he’s been a part of the UFC organization since the beginning, and he’ll be in the octagon when the company makes their network TV debut on November 12. CSAC Executive Officer George Dodd informed the UFC that, “there is a 99% chance” that McCarthy will be the referee for the UFC on FOX main event between Cain Velasquez and Junior dos Santos.

The news was first reported by MMAJunkie.com.

McCarthy, who retired from being a UFC referee after The Ultimate Fighter 6 Finale in December 2007, returned as the third man in the cage at UFC 117 in August 2010.

UFC President Dana White had previously stated that he wanted Herb Dean, who he believes is the best in the business, to oversee the main event title fight. Dean, along with Larry Landless will also be referee’s at the event although they have not been given fight assignments as of yet.
