In July 2026, former UFC champion Alex Pereira publicly condemned referee Herb Dean after a disputed decision at UFC Baku, alleging that Dean allowed fouls that altered the fight’s outcome. Pereira referenced a similar grievance from his own loss to Ciryl Gane and called for Dean’s removal. The controversy was amplified by a separate review by the California State Athletic Commission of a stoppage in an MVP MMA undercard bout, which upheld Dean’s call despite criticism.

By early August 2026, Pereira’s anger persisted following another incident at UFC Freedom 250, where illegal strikes to his head went unpenalized by Dean. Pereira reiterated his frustration, while also announcing plans to return to competition later in the year and targeting the winner of an upcoming heavyweight matchup. The ongoing debate highlights broader concerns within the MMA community about referee oversight and the role of athletic commissions in ensuring fair competition.
