Overview
- A run of disputed referee decisions has focused on veteran official Herb Dean after high‑profile fights that included the Ciryl Gane–Alex Pereira bout, Andre Fili’s complaint and the co‑main event at UFC Baku.
- At UFC Baku on June 27, Shara Magomedov repeatedly grabbed Michel Pereira’s hair, delivered an apparent eye poke and landed a groin strike that earned warnings from Dean but no point deductions.
- Fighters, coaches and podcasters have escalated criticism publicly with petitions and heated commentary accusing Dean of leniency, saying unpunished fouls changed fight momentum and outcomes.
- Veteran referee John “Big John” McCarthy defended Dean’s calls as consistent with the narrow unified‑rules definition of the back‑of‑the‑head, while UFC president Dana White said referee assignments and discipline are handled by state athletic commissions.
- Because commissions license and protect officials and discipline is rare without clear egregious evidence, the immediate outlook is for public debate and possible appeals rather than swift removals or rule changes.
