Ok, what you are about to see is something we have never seen before.
Sure, we have seen fighters go at it during the weigh-in prior to their fight but we have never seen one fighter go at his opponent with a flying knee.
Watch as the dude in a white t-shirt and jeans KOs his opponent momentarily with a flying knee as they are about to weigh in for their fight.

Yeah, this is not cool at all.
