I didn't get to see the game today but just watched a clip of the incident, and how ANYONE can say it's not a head butt is astonishing.
Quote from Robbie Savage on 606 as I heard it in the car "It should be a 10 game stadium ban, he's just head butted him for wanting to get the ball!"
And this is Soccer Saturday's opinion on the matter: https://www.youtube.com/watch?v=BhGUpVCW84I
If you're ever to be "head butted" and recieve a blow equal to what Pardew has done then you can count yourselves lucky.
They've rubbed faces, if that.
