Sheffield United captain Chris Morgan has been charged with violent conduct by the Football Association.
The charge against the 29-year-old defender relates to an incident involving Robin van Persie during the 1-0 win against Arsenal on Saturday.
Morgan appeared to strike the Arsenal forward out of sight of match referee Alan Wiley.
He has until 1800 GMT on Thursday to respond and a disciplinary commission will consider the case the next day.
Blades chairman Terry Robinson is to review video evidence of the incidence before deciding whether the club will contest the charge.
"It is most likely that Chris will appeal against this decision with the support of the club," Robinson told the club's website.
"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.
"The club will re-assess the video and make a final decision on Thursday.
"Whilst Sheffield United do no condone this sort of behaviour, we cannot reconcile this incident with violent conduct."
Centre-back Morgan was on the receiving end of a punch earlier this season, with Wigan's Lee McCulloch punished with a three-game ban.
United grabbed a vital three points on Saturday when they shocked London giants Arsenal with Christian Nade's winning goal just before half-time.
