The Nevada State Athletic Commission announced the referee and judging assignments for the two championship bouts at UFC 300 during a Tuesday meeting. Derek Cleary, Sal D’Amato and Ron McCarthy will serve as cageside judges for the bout. This will be the first time that Dean has officiated a UFC fight involving Pereira, but he did oversee Hill’s victory against Thiago Santos in August 2022.
Jason Herzog will be the referee for the strawweight championship clash between Weili Zhang and Xiaonan Yan, and Mike Bell, Ben Cartlidge and Chris Lee will serve as the cageside judges. This will be Herzog’s first time reffing one of Zhang’s fights, but he did officate Yan’s decision win over Claudia Gadelha in November 2020.
UFC 300 takes place on April 13 at the T-Mobile Arena in Las Vegas.
