The officials who will oversee the UFC 306 title fights were revealed Thursday during a monthly Nevada Athletic Commission meeting.

The Sept. 14 main event between bantamweight champion Sean O'Malley and Merab Dvalishvili at Sphere in Las Vegas will be officiated by Herb Dean, with the three judges set to be Mike Bell, Sal D’Amato and Chris Lee.

Mark Smith was selected as the referee for the co-main event between women’s flyweight champion Alexa Grasso and Valentina Shevchenko. Ben Cartlidge, Eric Colon and Ron McCarthy will be the three judges.

Each referee will be paid $5,000, and judges will receive $4,000 each.
