Most devastating KO you have ever seen?

[Mr.Easy]

Mike Tyson breaking Michael Jack Johnson's jaw!!!

[JmH Reborn]

The recent Montiel KO will leave an imprint in me for a long time. I mean the dude had a psuedo seizure and his face was left with a permanent indenture.

My son watches me in the gym when I train and we watched the Montiel fight and I was like "See son, if daddy puts his hands down, that's what happens"

[IronDanHamza]

Marciano-Walcott.

The most brutal KO I've ever seen.

[Travdog]

I'm going to go with Chin Checker Jaidon Codrington getting KO'd by Allan Green

[gamefrk]

Recently...Lebedev KO Roy Jones!! DAMN!

[Elotero]

Paul Williams getting KO'd by Martinez...that was disgusting..

Nigel Benn vs Russel Barker. Barker shouldnt even have been in the ring.
Sweat Pea teeing off on Hurtado.
Din-a-ling man KOing Nwodo. Nwodo looked like he died.

[IronDanHamza]

Eubank-Dos Santos is one of my favourites.

[Evil Abed]

[DTanc]

Best 1 round fight I can recall

MERCER KO'ING MORRISON

That s*** was crazy.

Everytime Morrison would try to go down, Mercer would just throw an uppercut to keep him standing lol

By far, the greatest KO of all time!

From the KO's I can remember I agree wholeheartedly!! BRUTAL!!
