Most brutal KO you have ever seen in your career of watching boxing?

[Daddy T]

Calzaghe slapped Manfredo so hard I thought he'd taken his head off.

[A-Wolf]

Hamed TKO4 Sanchez

Literally one of the hardest punchers of all time landing pumpkin blasting headshots on a very game competitor. I thought Augie might die, honestly. Thank goodness he was alright.

[deliveryman]

Wow, no one has mentioned Gatti vs Gamache yet?

[radioraheem]

I thought Pac was dead.

One of the worst KO's in boxing history. Knocked unconscious, fell face first, wasn't moving, and had to be awakened through smelling salts.

You weren't the only one who thought he was dead. Even fans in the Philippines were asking that same question, is he dead?

Crazy.

[Kuyukut]

all of floyd's opponents! oh wait... nevermind.

[Curtiz]

OMG OMG
