Knockouts that looked like the guy died?

[InvertedCross]

First one comes to mind is Barbozavs Etim when that kick landed Etim turned to stone it looked like he died he just looked lifeless.

Another one is Stout vs Edwards the way his head bounced off the Matt and the amount of time he was out for it looked pretty bad.

[BisexualMMA]

Didn't Arlovski seem dead after the Datsik fight too?

Matua looked like he would be brain dead very soon after the Tank fight.

Duffee against Mir? (already there I see)

CC vs Manbearpig.

This one ^ made me jump off the couch, and immediately came to mind when reading thread title.

I remember this one^ being pretty awesome too.

Belfort Linland was the worst ever imo

Linland did not look like he was going to wake up. It took several minutes to wake up. When he did wake up he looked as if he would be a quadriplegic.
Henderson Bisbing was also quite vicious.

 

[FrontNakedChoke]

Great responses so far. Here's mine.

 

[Hulk Brogan]

Cro cop getting crocop'd

 

[Rvd Slmr]

He never fought again after that fight.

Yes he did, four times.

Paul Daley's KO over Scott Smith is up there. Looks like he got taken out from a sniper bullet to the back of the head.

 

[roaringboy]

Yes he did, four times.

And was also starched by Lawler in one of those!
