From 'great referee' to resignation target: Herb Dean's fading reputation

Herb Dean, once regarded as the finest referee in mixed martial arts, is facing a fierce backlash. Repeated controversies over his officiating decisions have prompted fighters to call publicly for his removal, and a parody video mocking his refereeing style has added to the pressure.

Dean has worked the UFC octagon for more than two decades, but a series of disputes this year over stoppage timing and foul management have shaken confidence in him as an official.

MMA Fighting, a US combat sports outlet, reported Wednesday that UFC welterweight Joaquin Buckley had posted a training video parodying Dean's officiating style.

In the clip, Buckley hammers a heavy bag and asks a training partner to try to pull him away — mimicking the moment a referee separates an agitated fighter in a real bout. Buckley called it the "Herb Dean training method," a satirical dig at what critics describe as Dean's apparent hesitation when stopping fights.

Buckley did, however, express respect for Dean in the video's caption, choosing to address the recent controversy through humor rather than outright condemnation.

The latest wave of criticism was reignited at UFC 332 in Salt Lake City, Utah, on Oct. 3. Dean stopped the bout between King Green and Esteban Ribovics at the 4-minute, 8-second mark of the first round. Green had already been knocked down three times by Ribovics; when he hit the canvas again, Dean waved off the fight and declared a TKO.

Green protested vigorously the moment the bout ended, insisting he was still capable of continuing.

Reactions to Dean's call were divided. Some argued the stoppage was justified given the safety risk to a fighter who had been downed three times, while others said Green should have been given a chance to recover.

UFC CEO Dana White also weighed in at the post-fight press conference, acknowledging that Dean had been having a difficult year. White stopped short of calling the stoppage an outright error, however, noting that Green had been knocked down three times.

Criticism of Dean has also come from former UFC champions. Henry Cejudo, a two-division UFC champion, said on his podcast "Pound for Pound" on Monday that Dean should step down from refereeing.

Cejudo said he could not understand why Dean continued to be assigned fights, and criticized what he called a lack of accountability for officiating decisions. He particularly cited Dean's handling of an illegal knee on Dana White's Contender Series as evidence of poor judgment.

Former UFC welterweight title challenger Jorge Masvidal also joined the criticism. In a recent podcast interview, Masvidal said Dean appeared to hesitate at moments when he should be stopping a fight, and that it was time for him to step away.

Masvidal said a referee's most important duty is to protect the fighters, and that Dean failed to control situations with the calm and decisiveness the role demands.

The broader erosion of confidence in Dean began in earnest at UFC Freedom 250, held at the White House in June.

Alex Pereira suffered a second-round TKO loss to Ciryl Gane in the interim heavyweight title bout. Allegations that Gane had struck the back of Pereira's head late in the fight then put Dean's management of the bout under scrutiny.

Pereira pushed back, saying Dean had failed to stop the illegal strikes. He subsequently made public calls for Dean to be removed from UFC events.

Dean defended his call, explaining that not every part of the back of the head constitutes an illegal target zone. The official result of the fight was not changed.

Further controversy followed in August, when the reality series "The Ultimate Fighter 34" aired scenes showing confusion over a stoppage and a video review. Critics said the situation was handled poorly after Dean intervened and the bout had to be re-examined.

Dean is a familiar figure to Korean combat sports fans, having refereed not only in the UFC but also in Road FC on multiple occasions.

He is particularly remembered in Korea as the referee who watched Kim Jae-hoon — known as the "Yakuza Fighter" — unleash what fans dubbed the "52-punch barrage from hell." At Road FC 032 in Changsha, Hunan Province, China, in July 2016, sponsored by Xiaomi, Kim threw dozens of punches at Chinese opponent Zhang Jianjun. Most were absorbed by Zhang's guard and landed without meaningful effect.

Dean did not stop the fight during the barrage. Zhang was maintaining his guard and defending throughout, and while the punch count was high, the actual damage inflicted was minimal — a judgment most observers considered correct.

Dean also refereed Kim's bout at Road FC 027 in December 2015, in which Kim was knocked out by Aorigele in just 24 seconds. A moment from that fight also drew attention: after the final bell, Aorigele attempted to continue attacking, and Dean stepped in to restrain him.

Not everyone agrees with the criticism of Dean. Former UFC middleweight champion Israel Adesanya watched the Green-Ribovics bout and praised Dean's decision to stop the fight, saying that preventing further damage to a fighter who had already been knocked down three times was the right priority.

A referee must be willing to stop a fight to prevent serious injury, even when the fighter wants to continue. At the same time, a referee must not prematurely end a contest when a fighter is still defending effectively.

Dean was named Referee of the Year at the World MMA Awards for five consecutive years from 2010 to 2014, a run that cemented his standing as one of the sport's elite officials.

Yet the recent string of controversies has put that legacy under pressure. Calls for his resignation have been made openly, and crowds have booed him at events. Dean responded at length only to the fallout from the Pereira bout; since then, he has largely stayed silent.

Whether Dean can restore the reputation that once made him one of the most trusted referees in the sport remains to be seen.
