Please look for potentially dangerous. If a kid's knee is bent the way it is not supposed to bend....stop the match. That is potentially dangerous.
Takedown Machine,
Unfortunately, there will still be matches in high school where from the stands, potentially dangerous is obvious but the official does not call it. I saw one last weekend. It was nothing intentional from the top wrestler, it just turned into a very strange hold going for a cradle. When the match was over, the other wrestler was taken off on a back board for precaution. I have heard since then that he is fine. It was just unfortunate that the official didn't see it, but for some reason he didn't.
