A referee sent off five players in the dressing rooms after a post-match brawl in the League Two game between Bradford City and promotion-chasing Crawley Town.
"I can't believe this has happened," Bradford manager Phil Parkinson, who had three players shown red cards after the 2-1 home defeat on Tuesday night, told the BBC.
"I have never been in a situation before where a ref has come into the dressing room, pulled players on one side and sent them off. He wouldn't allow me in there."
Six Crawley players and one from Bradford were booked during the match with Bradford's Andrew Davies, who was sent off, now set for a five-match ban after being shown red cards twice previously this season.
