Single Hardest Punch Ever Landed

[The Old LefHook]

There must be some pretty good candidates here. I will start out with Tyson's pulverizing right that did in the white buffalo.

Marquez's couter punch that put pac to sleep and maravillas left that put the lights out on pwill

Okay, that might qualify for the hardest punch in that division. It was a one punch KO. Heavyweights have likely thrown the hardest punch ever, though.

Seriously, I do not see how anything but a one punch KO could even qualify in this contest.

Personally, I would judge the punch that felled the white Buffslo as harder than Marciano's shot that felled Walcott.

Some of those haymakers Foreman landed on Ali's body were awful hard, though not resulting in KOs..

The hookercut mercer landed on morrison when he was on his way down was scary. Also williams vs martinez, jackson vs Graham, hearns vs duran

[TBear]

Perhaps not the hardest ever but Tyson's left hook that brushed Berbick's head put him down three times.

honorable mention to Foreman lifting Frazier off the ground with a punch.

[Tom Cruise]

Foreman uppercut that decapitated Roman

[Sadiqkingofko]

Wlad against Brock or Austin

[ShoulderRoll]

Thomas Hearns' right hand bomb on Roberto Duran.
