A spokesman from the FA said: "When judging whether to take disciplinary action in this case, The FA has had to consider the challenge itself and not the outcome of it.
"The FA has been given express direction from FIFA that we cannot upgrade yellow cards to red. On this basis, we can only bring additional charges in the most exceptional cases and only it can be proved beyond doubt that the actions of a player were a deliberate attempt to injure and opponent.
"Having reviewed all available evidence in this case, including submissions made by Barnsley, there is no basis on which an additional charge could brought."
