Former Gillingham striker Mark McCammon is suing the club, claiming he was racially discriminated during his time there.
McCammon, a Barbados international, claims he and other black players were treated harsher than the white members of the squad in a landmark employment tribunal case. McCammon alleges that punishments for missing training, treatment of injuries and pay cuts following relegation were different for the black players.
In January 2010, McCammon spoke out against the tactics of then manager Mark Stimson, an outburst that saw him having to train with the youth team as punishment. The striker claims this was a way of trying to force him out of the club - an allegation Gillingham strenuously deny.
"The allegations made by Mark McCammon are wholly rejected by the club. It would not be appropriate for the club to comment further until the employment tribunal hearing has taken place," a club spokesman told the Daily Mail.
PFA chief executive Gordon Taylor says the organisation have tried to resolve the matter internally, but that it was not possible and therefore a tribunal would be needed.
His claims will be heard at Ashford employment tribunal in Kent later this year.
