Newcastle manager Alan Pardew has expressed his regret in the wake of the extraordinary flashpoint which overshadowed his team's 4-1 Barclays Premier League win at Hull.
The game's main talking point arrived in the 72nd minute when Hull midfielder David Meyler barged into Pardew as he looked to retrieve the ball for a throw-in.
The Newcastle manager, no stranger to touchline altercations, squared up to the former Sunderland midfielder before appearing to move his head in the direction of the Irishman.
Referee Kevin Friend certainly viewed it as a serious incident and sent Pardew to the stands, with the FA sure to take a close look at the altercation in the coming days.
Pardew told Sky Sports News afterwards: "It was a heat of the moment thing - I massively regret it."
"I didn't meant to do anything aggressive but I moved my head forward and that's enough."It's a shame because it took the gloss off a fantastic performance from us. That's really upsetting."
