Veteran referee Herb Dean was selected Thursday to oversee UFC 191's flyweight title fight on Sept. 5 between Demetrious Johnson and John Dodson.
The selection was made at a meeting of the Nevada Athletic Commission in Las Vegas. Dean was unanimously approved by the commissioners.
Johnson (22-2-1), the defending UFC flyweight champion, previously fought Dodson in Jan. 2013. The fight was the closest of Johnson's reign as champion, however Johnson emerged with a narrow unanimous decision win.
Dodson (17-6) has won three fights since to earn his way to a rematch, highlighted by a pair of finishes over Darrell Montague and John Moraga.
