It's hard to say which is the greatest knock-out we've ever seen - they're all different. But this one is right up there.
You get the huge haymakers that have so much power behind them they put the lights out straight away, like when Mason Menard through an overhand right on Dominican lightweight Eudy Bernardo that left him in a neck brace.

Then you get straight shots like this battering ram of a right hand from Anthony Joshua on the unfortunate Raphael Zumbano Love.
Who could forget Conor McGregor's 'precision beats power' punch that put Jose Aldo to sleep and brought his stranglehold on the UFC featherweight division to a crushing end?

But there's another knock-out that could eclipse even these and it came at the hands of a young fighter people are calling 'The GGG of the Cruiserweight Division'.
That's GGG - Gennady Gennadyevich Golovkin - the Kazakh middleweight with a 91.7% KO ratio who's never even been knocked down in 375 fights. You read that right [they must have included playground scraps].
The 22-year-old Russian goes by the name of 'Iron' Murat Gassiev and he's been tearing everything up in his path, with 17 KOs in 23 fights.
But his ruthless KO of Jordan Shimmell inside the first round with surely be his best to date. He lands the left hook right on the button which puts Shimmell out cold and almost out of the ring.
What makes it such an incredible KO is how tight and compact the hook is but just how much power he generates. The venomous snap on that shot is a thing of beauty.
Gassiev, who is trained by the same guy that has masterminded GGG's rise to the top, will be one to watch in the division for sure.
