While the world continues to be in awe of Ronda Rousey's knockout ability, make sure you don't sleep on this impressive KO.

Izu Ugonoh and Will Quarrie stepped into the ring on Saturday night in New Zealand, but only one of them managed to step out. That's because one was hit so hard he fell out.

Look at the devastating right-handed blow Ugonog unleashes on Quarrie in the second round. He literally knocks him out -- out of the ring, that is. Quarrie drops through some of the rings and his head flaps near the scorer's table.

That's as crushing a shot as you're going to see from a pugilist. Heck, that's a punch you probably won't even see in any of the Rocky movies.
