The referee steps in to stop the match and knocks out the fighter on the ground himself

In MMA, a fighter managed the feat of losing twice in the same bout. Knocked out in a matter of seconds by his opponent, he was already on the ground when the referee stepped in to stop the fight. Except that the referee got caught up in the action himself and unintentionally landed a second blow on the already dazed fighter. Final score: KO by the opponent, then KO by the referee.
