Grimsbly Town been fined £15,000 for failing to control supporters after violence erupted at a League Two game.
More than hundred supporters clashed at the Grimsby Town v Port Vale game on 10 March 2018.
An FA hearing found Grimsby Town had failed to act on police intelligence about possible violence and had an “insufficient number of stewards” at the match.
The club has refused to comment on the report’s findings.
The FA’s report said violence broke out after both sets of fans charged each other after Grimsby Town scored a last minute equaliser.
In his match report, referee Sebastian Stockbridge said: “Before we kicked off to restart the game, supporters from both clubs charged towards each in a violent and confrontational manner.
“They came over the advertising boards and on to the field of play. Stewards attempted to stop them and remove them from the field of play, however there were too many supporters for the few stewards.”
The fine for failing to control supporters does not condone the actions of a small number of idiotic Port Vale fans who seemed intent on violence and disorder and brought shame onto their club.
