Sheffield United captain Chris Morgan has been found guilty of violent conduct and hit with a three-match suspension by the Football Association.
Morgan appeared to strike Robin van Persie out of sight of referee Alan Wiley during the Blades' 1-0 victory over Arsenal last weekend.
The decision to hit United's defensive lynchpin with a three-game ban is certain to anger the Blades, who were contesting the charge of violent conduct.
Ironically, Morgan was recently on the receiving end of a blow from Lee McCulloch which led to the Wigan Athletic forward receiving a three-match ban.
The combative United skipper also looked to be caught by Aston Villa striker Juan Pablo Angel in a 2-2 draw between the sides in early December.
Earlier in the day, Blades chairman Terry Robinson had said: "It is most likely that Chris will appeal against this decision with the support of the club.
"The incident was seen by many in the ground and on television, but in comparison with the incidents in our recent games against Aston Villa and Wigan was relatively trivial.
"While Sheffield United do no condone this sort of behaviour, we cannot reconcile this incident with violent conduct."
