Rab, if it takes 5 days for the result of the appeal to be decided, then there is absolutely no way Krasic could be suspended for the Milan game.
Think about it: 5 days from now we are Sunday. If that's when they make the final decision (impossible since it's a Sunday, but still), then how can they suspend a player before that date. Our Milan game is on Saturday.
It would be quite something to have the suspension canceled (from 2 games to 0), only to realise that 1 game has passed in the meantime, wouldn't you agree?
My guess is that the result of the appeal will be decided on Thursday, or Friday at the latest. Just in time for it to count (whatever the outcome) for the Milan game.
