Other mistake: In the semi-final where John Lawrence fights against Darryl Vidal, the female referee has major problems of what to do. When Lawrence gets his first point, the referee first raises her red flag (Vidal is wearing the red ribbon) but then swiftly changes her mind. And when Lawrence gets his third point, the female referee again incorrectly raises her red flag.
Other mistake: When the referee is going over the rules to Daniel and Johnny, he tells them both that kicks to the face are illegal. However, when Daniel is in the Crane position, Johnny charges and gets kicked right in the face. This should have disqualified Daniel immediately and made Johnny the winner.
