The Football Association has charged Newcastle United manager Alan Pardew with improper conduct.
The charge relates to the 52-year-old's actions on Saturday afternoon at the KC Stadium, where he headbutted Hull City midfielder David Meyler following a short disagreement between the pair on the touchline.
In a statement, the FA said: "It is alleged that in the 72nd minute of the fixture, Pardew was involved in an incident with a Hull City player that amounted to improper conduct.
"Due to the serious violent and/or aggressive nature of the reported behaviour this case has been designated as non-standard."
Pardew, who has been informed that he will not face any criminal proceedings, has been given until 6pm on Thursday to respond to the charge.
