Ray Mercer vs Tommy Morrison. Still uneasy watching that today. The referee should have stepped in far far sooner. Any others spring to mind?
Mercer vs Morrison was the 1st one I thought of too when I read the thread title. Canelo vs Khan, Garcia vs Zlaticanin and Povetkin vs Price for some more recent examples.
Ha, that was the very 1st one to pop in my head when i saw your question. From recent memory David Price when he got knocked out by Teper. That was an ugly one.
From recent times - Whyte v Browne Wilder vs Spilzka Wilder v Stiverne 2 Povetkin vs Price Maybe Allen vs Webb?
Roy Jones Jr knocking out Art Serwano, if you haven't seen this KO, it's Serwano's face, it looks like he has some sort of seizure or something, zombie faced, very freaky.
I remember Roberto Duran walking to the neutral corner looking for his corner men at the end of round 1.. He was confused at not seeing his men there and had to be hand-led back to his corner, with Hearns looking on in disbelief. Hearns actually said before the fight that he would knock him out in 2 rounds and that is exactly why he fought at such a feverish pace from the opening bell. The last right hand and the noise it made... It still makes me feel sickly and unwell to this day. Hey, I got to say this; how in the hell was Duran not knocked unconscious from it and how did he still get back up within 1 minute... Incredible that he is not a vegetable eating meals through a straw
