Ok, thanks and H3 seems to have jumbled thing together. Carding a player for contacting a keeper is very common in open field play, but in a crowd in the box on the ground with ball not in control it is harder to get a ref to stop play, not saying it should not have been carded but my son had his hand stomped in the box trying to corral a loose ball, no card, two broken fingers but no card.
Got to ask yourself; Had it been the Clover keeper hit by the Lancaster striker would you want a card? If your player was trying to get a loose ball in the box and Lancaster keeper was stepped on would you be calling for a card for player safety?
