Black has to be severely punished for this one.
I don't mind if he gets a yellow for a robust challenge here and there, but when its for picking the ball up and booting it away right in front of the ref, as if to say "Go on then, send me off", then there is no place for him in our team.
Edit : just seen the footage. Just after the half-time whistle went, he drop-kicked the ball from the centre circle to one of the goals. The ref gives him a yellow. As Blackie gets to the touchline, he picks up another ball and does exactly the same thing. He tried to argue that the 2nd one was not the match ball, it was actually for the half-time youngsters game, and he just getting it on to the pitch for them. Perhaps it could be seen as harsh, but what stupid thing to do, it gave the ref an easy opportunity to book him again.
