This stuff happens in games. But let's not pretend a player in that situation doesn't know what he is doing. He made a bad decision and a decent suspension will hopefully stop him making the same one again.Did you actually see how fast the entire incident transpired?
You're also forgetting that he received a free kick for holding the ball.
It happened so quickly the umpires didn't even notice the 'vile act'. What hope did Sicily have to change the outcome other than to not tackle him at all in the final quarter of a close game?
