Spireites have launched an investigation after black players were subjected to racist taunts.
Chesterfield FC has been asked by the FA to launch a full probe into the events after the final whistle in Saturday’s game at Port Vale.
As the teams left the pitch, black players had monkey chants and racist language hurled at them from at least one Port Vale supporter as he left the pitch following the Spireites’ 2-1 League One victory on Saturday .
Striker Armand Gnanduillet had to be held back by stewards and colleagues as manager Paul Cook tried to calm the clearly agitated French-born Ivorian down.
Chesterfield chief executive Chris Turner said: “Any form of racism cannot be tolerated. We have been asked by The FA to launch a full investigation, which will involve speaking to our players.
“I spoke to Port Vale chairman Norman Smurthwaite after the match and he said they would hold their own investigation.
“We will make no further comment on the matter while the investigation is taking place.”
