Choi Mu-Bae was a big winner at Sengoku 7 over Dave Herman only he didn't know it for a few seconds. Watching the fight, you initially thought Choi collapsed because of exhaustion but a closer look shows that his cornerman tackled him and actually knocked him out. Watch around 9:20 of the video, Choi is out cold.
His handlers can't even remove his mouthpiece! It's amazing how quickly Herman gassed. He had nothing in the tank a few minutes into the second round. Maybe he was intimidated by the sneaks and ankle socks look by Choi.
