The same ref who goes over to the VAR screen to make the final decision, the same ref who decided Gabriel and Mandueke head butts did not cause fatal injuries but Yarmo's chest pump did. EVERYTHING is looked at, the ref can have a chat and say, what did I miss there. All 3 incidents we are talking about were studied by VAR and had a chat with the ref, he saw Macallister had taken a bullet shot to the head and was mortally injured, he saw him bounce up to create more problems. That is on him.
One weeks ref is next weeks VAR, they are inseperable.
