Maybe I don't understand this fight... But there was no tap-out and no pin. Why was the fight stopped?
-Fetter
Chuck got knocked down and if you'll notice, he wasn't able to defend himself. His arms were laying to the side and Rampage was landing blows. Big John or any other ref will stop the fight if one of the fighters is either knocked out or are unable to defend themselves.
Big John did exactly what a ref should have done, protect the fighters. When Chuck got tagged with the right and went down, he defended until he was hit the 3rd time, then Chuck went flat, and did not defend. If you look at the replays, when Chuck got up, he was asking what happened. Chuck was clearly dazed and not all there.
Props to Big John for stopping the fight when he did, it would have gotten really ugly if he didn't.
