Boxers must accept what the reality is. Bun Hoeurn should deserve the title because the opponent was knocked down seriously unconsciously. In addition, when the referee asked him to move forward, he couldn't do so. Therefore, the referee did the right thing in the ring.
Everyone makes a mistake. The only way to make thing right is a Rematch. We can not blame the referee. He thought he was doing the right thing at that moment to protect the fighter. So, let’s not blame anyone. Rematch is the only option.
