Video: Joaquin Buckley creates ‘Herb Dean drill’ in homage to controversial UFC referee

Dean is one of the most experienced referees in the UFC, having worked for the promotion for over two decades in addition to overseeing bouts for countless other promotions across the globe. However, his reputation has taken a major hit in recent years as multiple fighters have questioned his judgment, from former two-division champion Alex Pereira slamming Dean for missing fouls at the conclusion of his UFC White House loss to Ciryl Gane, to The Ultimate Fighter 34 contestant Xavier Franklin calling Dean out for a refereeing debacle that might have cost him a spot in the tournament finals.
