The 52-year-old clashed on the sidelines with Hull City midfielder David Meyler, and is set to face severe punishments for an incident that soured Newcastle's 4-1 victory
Pardew stole the headlines for all the wrong reasons in the 72nd minute when he was sent off after appearing to move his head forward and strike Meyler, who was booked for his part in the incident.
The 52-year-old's actions overshadowed an excellent performance from Newcastle, although the former West Ham boss has since apologised for his actions.
"I apologise to [Meyler], everyone at Hull and particularly my own fans. From now on I’m going to have to sit down and keep out of the way because that is my second incident that I’ve been involved in this year," said the Toon boos afterwards.
"I’m not stupid enough to expect no punishment. I’ll have to accept what comes my way."
But, despite expressing his regret, Pardew appears set to face action from the FA after a spokesperson confirmed to Perform that the governing body will be examining the matter.
Pardew escaped punishment from the FA back in January following a touchline confrontation with Manchester City manager Manuel Pellegrini.
However, Pardew was "reminded of his responsibilities" after that spat and now looks likely to face a lengthy spell away from the dugout.
