Here's another Rubin Carter KO, knocking out big puncher Florentino Fernandez. (Brutal KO)

Marciano vs Walcott

'Hurricane' Carter knocks out Florentino Fernandez 5:18

I say BS! Pacs Ko of Hatton was not a one punch KO Hatton was down and out of it two times in the first to me a one punch ko is a tyson KO or am I getting way too technical feel free to correct me Your right, it was a great KO, but Hatton had already been hurt like three times in round one.

lol, Julian Jackson would be losing the fight and would be able to turn it around with just one punch.

Michael Spinks-Marvin Johnson. I can't find a clip of it on youtube. Here are some others.

Definitely not a 1punch KO but watchin Hearns work that jab is a thing of beauty. Best Jab in boxing history IMO Hearns is so underrated here as a boxer, it isn't even funny. He is downplayed because of his losses to Hagler and Sugar Ray. But people forget he had outboxed Leonard and broke his eye socket, and punched a big cut into Hagler's head. He also carried his power into every weight weight class he entered.

Nah, I finally found the clip. Not necessarily one punch KO since it was two right hands, but a KO like this is note worthy :D. Yep! Definitely not a 1punch KO but watchin Hearns work that jab is a thing of beauty. Best Jab in boxing history IMO

It really does sound like the Duran KO tho lol Nah, I finally found the clip. Not necessarily one punch KO since it was two right hands, but a KO like this is note worthy :D. Do you mean Hearns vs Pipino Cuevas? Yep!

We're getting alot of really good additions. Keep it up guys. And if possible post video of your suggestion. Thanx.

lol, it was not Duran, I would have obviously remembered that. It was on the Spanish version of ESPN a few times. It really does sound like the Duran KO tho lol

Jones Junior vs the guy who looked like the devil, with his crazy eyes when he was KOed. James Toney vs Prince Charles Williams Calvin Brock vs Zuri Lawrence

Donaire vs Darchinyan James Thunder vs Crawford Grimsley

Do you mean Hearns vs Pipino Cuevas? Here's one of the best in my opinion:
