Sean O’Malley and Merab Dvalishvili will have a familiar set of eyes on them in their title clash.

Referee Herb Dean serves as the third man in the cage for the UFC 306 headlining bout between the bantamweight champion O’Malley and Dvalishvili, which takes place at Sphere in Las Vegas on Sept. 14. Dean’s assignment was made official at a meeting of the Nevada Athletic Commission on Thursday.

The judges for the UFC 306 main event are Mike Bell, Sal D’Amato, and Chris Lee.

Overseeing the co-main event trilogy bout between flyweight champion Alexa Grasso and Valentina Shevchenko is referee Mark Smith. The judges for this contest are Ben Cartlidge, Eric Colon, and Ron McCarthy.

A high-profile boxing bout between Canelo Alvarez and Edgar Berlanga also takes place on Sept. 14 in Las Vegas, and Thursday’s NAC meeting saw officials determined for that headlining bout at T-Mobile Arena. Harvey Dock serves as the referee, with Max DeLuca, David Sutherland, and Steve Weisfeld assigned as judges for the 12-round title fight.
