Wow is all I can say! The referee unfortunately made the right call in the end. If an opponent is injured from an illegal hold and can not continue he wins the match. I could not tell if it was illegal or not from the camera but it looks to me as if the coach pulled a fast one here. It is sad that the officials had to be escorted out because they did the right call. If a coach says that their kid can not go the referee's hands are tied. I believe the coaches’ code of ethics is in play here.
