Has there ever been a fight where?

someone who was on their back knocked the person out?

 

yeah, I've seen one on Rumble on the rock, but the guy was dqed sine it was illegal to head kick when you're down

 

I think I recall seeing an upkick in one of the earlier UFC's that did some damage, but I cant put a finger on it

 

Renzo Gracie knocked out Oleg Taktarov from the bottom. It actually happens plenty of times, particularly with elbows.

 

was it an elbow strike from gracie?

because ive watched alot of UFC and Pride and I still havent seen any...ive seen guys get rocked

if anyone has a video clip post that

 

He used the heel of his foot.

 

Was that part of their rules back then, or is it still enforced today?
