The referees and judges for the UFC 239 main and co-main events in Las Vegas have now been assigned following a Nevada State Athletic Commission meeting on Wednesday.
Veteran referee Herb Dean will be the third man in the octagon when light heavyweight champion Jon Jones looks to defend his title against Thiago Santos in the main event at UFC 239 on July 6.
Derek Cleary, Mike Bell and Junichiro Kamijo were assigned as judges for the Jones vs. Santos fight as well.
The Nevada Commission also granted Jones his full fight license to compete in the state that will remain in effect until the end of the years.
