He pushed him away after the headbutt. It's not like it was a reactionary movement.
Meyler pushed Pardew first not after. Also wasn't a head butt. Have a look at the replays of incident. Pardew did the "modern footballer" thing of pushing head into face of Meyler but clearly and definitely not a head butt.
Meyler rightly booked for the push on Pardew which effectively caused the whole thing to kick off.
Pardew rightly sent to the stand for his stupid reaction which was totally out of order. Pardew will no doubt get a fine and a ban and again rightly so as no excuse for his actions.
That being said anyone trying to claim that was a head butt has clearly never seen a head butt or is just biased against Pardew or (like the media) are just trying to cause trouble or manufacture a story.
... wasn't Sagbo sent off for a simulated headbutt?
you can't be doing that, no matter who you are.. why didn't Pards just move out of the way?
no! he thought he'd be a **** and stand his ground.
Not sure which bit of what I said you are arguing with. Also not sure what Sagbo has to do with this particularly as Pardew was essentially sent off/ sent to the stands. Also you may notice that I did say Pardew's actions were totally out of order.
The points I was attempting to correct are that Pardew did not head butt Meyler and that Meyler pushed Pardew first.
Got a lot of time for Pardew. Regardless of what people think, he is a top manager. One of the best I've worked with.

Meyler is as out of order as Pardew is.
Handbags.
sorry I wasn't meaning to sound like I was arguing.. I kinda wrote that for my Hull Tigers bretheren.
Pardew's a ****, he was a **** when he was at Charlton and he's an even bigger **** now.
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!"
