Newcastle boss Alan Pardew is not expected to contest an English Football Association charge over his headbutt on Hull midfielder David Meyler.
It is understood the 52-year-old will accept the charge of improper conduct announced on Monday after headbutting Meyler on the touchline at the KC Stadium on Saturday.
Pardew has until 6pm on Thursday to respond, and has the right to request a personal hearing to give himself an opportunity to explain his actions.
Pardew apologised immediately after the game, which his side won 4-1, but was fined £100,000 and handed a formal warning by the Magpies hours later.
He is likely to receive a significant further penalty if he either accepts or is convicted on the English FA charge, and that could include a stadium ban.
However, he will not face criminal charges over the incident with Humberside Police having confirmed neither Meyler nor Hull have made a complaint.
Meyler is on international duty with the Republic of Ireland ahead of tonight's friendly with Serbia at the Aviva Stadium.
