Poyet said at the time: "Andy D'Urso is not good enough for us and I don't want to see him at a Leeds match again."
The comments came after Leeds' second round Carling Cup defeat to Portsmouth.
Poyet has until October 4 to appeal. Leeds lost the tie at Fratton Park 3-0 and Poyet, who was sent off by D'Urso during his playing career, added: "He can't forget things he's done to us in the past."
