According to the rules, the match clearly should have been called. I can tell you that it was not my sons desire to end his high school career 15 seconds into the state championship and I do not think he was in the right frame of mind to make the decision himself as he was very disoriented. By the rules it clearly states that if an athlete suffers from a concussion or head injury they should be immediately removed from the competition. I do not know who makes the call but I can tell you that anyone who falls head first onto concrete and as a result requires stitches on their head should if nothing else be deemed a head injury.
