In any case where the referee decides that the contestants are not honestly competing, that the knockdown is a “dive,” or the foul a prearranged termination of the bout, the referee shall not finish the knockdown count or disqualify for fouling or render a decision, but shall stop the bout not later than before the end of the last round and order purses of both boxers held pending investigation and disposition of the funds by the commission. The announcer shall inform the audience that no decision has been rendered.
