Newcastle United have expressed their disappointment about the objectionable behaviour of manager Alan Pardew during the 4-1 win in their Premier League fixture against Hull City at the KC Stadium on Saturday.

In the 72nd minute, the 52-year-old aimed a headbutt at the Tigers' midfielder David Meyler. The incident forced the match referee Kevin Friend to send the Englishman to the stands.

Despite issuing an apology after the game, Pardew has been handed a fine of £100,000 by the club along with a formal warning for his erratic misconduct.

The statement on the club's official website read, "Newcastle United are disappointed with the actions of its manager Alan Pardew this afternoon (Saturday, March 1). His behaviour was unacceptable and is not the behaviour we expect from the manager of Newcastle United.

"It is most disappointing that this incident has taken the focus away from what was a fantastic performance by the team and an excellent result away from home which leaves the club in eighth place in the Barclays Premier League. Sadly, the headlines tomorrow will not be focused on the result or the efforts of the players, but instead on the actions of our manager.

"Alan unreservedly apologised immediately following the game to the player, to Hull City Football Club and its fans, and to the fans of Newcastle United.

"We have held discussions this evening with Alan who has offered his sincere apologies to the Club and it is clear he deeply regrets his actions. Alan has accepted a formal warning from the Club in relation to his behaviour today and also a Club fine of £100,000.

"The Club is now drawing a line under this matter and will be making no further comment."

However, Pardew's expression of regret does not stop the Football Association from further probing into the matter as chairman Greg Dyke has confirmed that the FA will investigate into the incident.

This is not the first time this year that the Newcastle boss finds himself in hot water. Pardew had apologised after indulging in a touchline spat and aiming insults at Manchester City manager Manuel Pellegrini in January this year.
