Seemed a bit fishy to me as well, I believe the announcer was watching an entirely different fight than I, he's talkin about all these massive repeated power shots doing irriversable damage and all I saw was one short punch that possibly connected followed by several more short punches that all appeared to miss.
Hey, maybe it was staged? Naaaawwwwww that kind of stuff never happens in "professional" entertainment...um.....oh.... I mean sports, does it?
Horrible fight. and the ref stopped it too early. This is why UFC is the #1 name in ultimate fighting
