The guy being put to sleep is Charles "Krazy Horse" Bennett, he's from right up the road in Ocala, Fl. This may come as a surprise but he's also absolutely bat shit crazy. This happened after Pride FC event and after he woke up he knocked Wanderlei Silva out.
Here's his side of the story if you're interested.
hes never fought Silva...he put some other dude in arm bar and made him tap out the day of this video.
