One of the most BRUTAL ko's I have ever seen it was on Rios/Abril undercard

DAMN! I always hope that if a fight ends early that it's with a body shot.

My favorite KO eva :D

Hearns-Duran was a nasty one too. @ 11:08 nice find dude ya Tommy the hitman Hearns is one of my favorites of all-time.

...career ended

Williams doesn't remember much tho... :)

The Sergio M/Williams was harder...but that was a scary hit..his neck snapped back in a bad way. agreed I think if this knockout though happened in the center of the ring and dude went straight down instead of being held up by ropes people would think it was a worse knockout. Martinez ko of Williams was one of the hardest I have ever seen though. man just listen to that shot god damnnnnnnnnnnnn

That some badass hit. All them man boob power from Butterbean went in that punch.
