Alex Pereira has been flooding his social media with posts demanding action against referee Herb Dean following his fight with Ciryl Gane, alleging that Dean failed to intervene when illegal strikes to the back of the head were landed. Pereira also reposted a video of boxer Prichard Colon, who suffered a severe brain injury as a result of repeated rabbit punches, to underscore the danger of ignoring such fouls. The 55-year-old Dean, widely credited with helping systematize modern MMA rules, has faced renewed scrutiny over his focus and attentiveness during fights.
Alex Pereira has taken to social media in the days following UFC 250 to publicly demand the dismissal of veteran referee Herb Dean, accusing him of failing to stop illegal strikes to the back of the head during his fight with Ciryl Gane.
The reigning UFC Light Heavyweight Champion, Pereira holds a 13-4 record and carries the kind of finishing power that makes clean officiating especially consequential. The 38-year-old Brazilian, who stands six-foot-four with a 79-inch reach, lands 5.16 significant strikes per minute at 62 percent accuracy — numbers that reflect how dangerous exchanges in his fights can become in short order. He has been emphatic in his posts, going as far as resharing footage of boxer Prichard Colon, who sustained a catastrophic brain injury from repeated rabbit punches, to illustrate what he believes is at stake when referees allow such shots to go unchecked.
Gane, his opponent in the bout, is ranked second in the Heavyweight division with a 14-2 record. The 36-year-old Frenchman out of MMA Factory is one of the most technically refined strikers in the sport, posting 5.29 significant strikes per minute at 61 percent accuracy and boasting an 81-inch reach that gives him a two-inch advantage over Pereira.
Dean, who is 55 years old and widely recognized for his contributions to formalizing modern MMA officiating standards, has faced criticism before regarding his attentiveness inside the cage. Pereira's campaign has renewed that scrutiny sharply.
Why it matters
- Pereira is the sitting Light Heavyweight Champion, giving his complaints significant platform weight
- Illegal strikes to the back of the head are one of MMA's most debated and inconsistently enforced fouls
- The episode renews a broader conversation about referee accountability and whether formal review mechanisms are sufficient
- Dean is among the sport's most prominent officials, meaning any sustained pressure carries institutional implications
