The Nevada State Athletic Commission (NSAC) has appointed veteran referees "Big" John McCarthy and Herb Dean to oversee the headlining and co-headlining bouts of UFC 194 on Dec. 12, according to MMAFighting.com's Shaun Al-Shatti.
A referee since UFC 2, McCarthy will be the third man in the cage when Jose Aldo and Conor McGregor finally sling fists for the UFC featherweight title. Derek Cleary, Sal D'Amato, and Junichiro Kamijo will serve as judges for the bout.
When Chris Weidman and Luke Rockhold meet with the middleweight strap hanging in the balance, Dean will officiate the high-stakes proceedings. Should Rockhold and Weidman battle to the 25-minute time limit, judges Chris Lee, Adelaide Byrd, and Marcos Rosales will render the decision.
UFC 194 will take place at the MGM Grand Garden Arena in Las Vegas.
