I agree with this as well. Also punishment for players who surround the ref. IMO they should make it like rugby union where only the captain can approach the ref.
Yesterday, Cohen actually did do himself an injury. Seemed innocuous at the time, but he had to be stretchered off. Thing is, the ref was right there, he could see that it wasn't a head injury, and the play was developing. No need to stop the play, and we didn't.
Although, technically, Ward did eventually put the ball out of play by slotting it into the net.
