Brett Cook is a hockey player for Nipissing University in Canada. Or I guess I should say WAS a hockey player for Nipissing University in Canada. He is no longer because recently he punched a ref right in his face.
According to the YouTube video:
The incident occurred following a third-period scrap between Cook and a UQTR player. Piche (the linesman) grabbed Cook and attempted to direct him towards the penalty box when another scrum broke out.
