I agree that Young showed great duty of care. Are you really going to argue that a professional umpire could not be expected to know what to do in this instance?I reckon it was such an unusual tackle no-one really knew what to do, even the players.
The lad did really well to take care in that situation as well, could have been a really nasty injury.
Player is tackled, tries to break tackle, can’t break tackle, makes no attempt to dispose of ball correctly. Pretty obvious.
The umpire is a professional remember. Surely he has seen similar actions once or twice during his professional career.
