I think we can get carried away with this quite easily given the outcome - as @RustyRef says it's clearly excessive force etc. Easy red, but I'm not on the massive suspension bandwagon. The laws cover this and I'm sorry his leg is broken, but's it "just" serious foul play.
Flicking a red card out of a refs hand = 5 game ban OR snapping someones Tib and Fib in a cowards challenge (8-12 months out of the game) May never play again... 3 games ban.... do me a favour, get real FA !!!!
