Newcastle manager Alan Pardew is facing a nervous wait to discover what action the England Football Association will take following his headbutt on an opposition player.
The Magpies boss was involved in the nasty sideline altercation when he clashed with Hull's David Meyler during his side's 4-1 away win on Sunday.
Pardew was fined $200,000 by Newcastle, who stopped short of sacking the fiery Englishman.
FA chairman Greg Dyke said in the aftermath of the incident that "clearly it looks serious and we will investigate it".
A lengthy touchline ban seems all but inevitable but disciplinary officials at the FA, English football's governing body, will first consider referee Kevin Friend's match report before deciding what action to take.
It is not the first time the 52-year-old Pardew had been involved in an unsavoury incident on the touchline, who was given a two-game ban in 2012 for pushing an assistant referee.
