The most brutal KO you've ever seen?

Hearns Duran was b-r-u-t-a-l. The thud of that punch was heard to the moon.

Gatti vs Gamachi has to be one of the scariest KO's ever. That was damn near decapitation.

Tyson had some pretty brutal knockouts. Rahman knocking out Lewis was pretty bad. Lewis didn't know what the hell hit him that night lol

figured i bump this, just to see. id have to say Mercer - Morrison / Tua - Ruiz / Pac - Hatton from what ive seen so far :D keep em coming guys!

Vince Pettway vs Simon Brown

I havent see too much of the oldtimers, so i cant really speak further back than the Ali-Frazier times.. but from what i know i'd say Ray Mercers brutal 5th round KO over Tommy Morrison is the worst. How about you? post some of the worst knockouts youve ever seen :D That's the first one that popped into my head. Tua's KO of Ruiz was pretty brutal as well, the last couple where the ropes were holding him up.

Gatti over Gamache was scary brutal.

holy sh*t that last one there was brutal ass hell :o shouldnt the referee have stopped it a lot eariler?

Hopkins vs. Lipsey Great call on Hopkins-Lipsey... that fight and his systematic beatdown of Glen Johnson is vintage B-Hop. Some great posts in here. Jackson-Graham is perhaps my favorite KO of all time, especially the announcer's commentary along with it ("OH NO!!! THAT'S WHAT WE WERE WORRIED ABOUT!"). If nothing else, the very definition of a one-punch knockout Trying to find some that haven't already been mentioned: Vincent Pettway-Simon Brown Floyd Patterson-Ingo Johannsen II (KO is at about the 2:15 mark) Darnell Wilson-Emmanuel Nwodo

Arturo Gatti's KO of Joey Gamache. Absolutely brutal.

Montell Griffin, second fight. Poet You sure? i dont think it was him :O Or if it was him, i might be thinking of someone else.. in my head it is some C-class fighter. i might be wrong though.

Pac Hatton was a brutal KO. Duno who these two are but this is a naaasty KO. http://www.youtube.com/watch?v=JH5wEEFfer0

Abraham vs Khoren Gevor was vicious. And not mentioned yet, I believe... beat me to it. Abraham made Gevors head look like a bobblehead.

Julian Jackson-Herol Graham. The way Graham seemed to go down slowly, while completely out of it, was fukking scary.

y'all remember when roy knocked that dude out and his eyes rolled back and his mouth was wide open like he was having a stroke for a sec I'd say that was pretty brutal I remember, anyone know his name?

frasier vs foster at 3:15 Jesus....those 2 left hooks back to back by Frazier were fast as hell. too bad Foster didn't carry his power to HW, but still a great fighter.

Bob Foster Vs. Mike Quarry :boxing: foster had frightning 1 punch KO.

foreman should have been in that Video...He vs moore Just because he got a belt with ko considering his age.

the ones that quickly come to mind are: Hearns-Duran Sam peter-Williams Maskaev-Rahman
