Wasn't a real big KD, it was more like Judah got stung and was being backed against the ropes and took a knee instead of the follow-up barrage. It was a slightly blocked straight punch though, didn't look strong enough to really hurt him, but he was really out of position after taking it.. taking a knee was probably smart.. I don't think he was seriously hurt.
Epic video! I wish I had the creativity to come up with a video like this... I dig the banjo portion of the song
Here's a clip of the Judah-Matthysse fight but I don't think this KD was the KD... http://youtubeboxingvideos.blogspot.com/2010/11/zab-judah-vs-lucas-matthysse-fight.html
