In the history of the sport, what's the hardest landed punch you've ever witnessed?

Ibeabuchi/Byrd - That uppercut would have KO'd any HW today...vicious punch Hearns/Duran - The fact that Duran was coming off the ropes when Hearns hit him with that violent punch made it much more brutal. As for punches that were brutal but didn't KO the other guy I'd have to say Holmes/Shavers and Mugabi/Hagler. Hagler ate a monsterous uppercut from one of the hardest punchers the sport has ever seen...not to mention that Mugabi was 25-0...and he straight up ate it and kept coming. I don't know how Holmes managed to get up from that shot Shavers hit him with. Seconded. Duran was asleep before he hit the deck.

Hearns-DURAN!!! Tito-Vargas and Joppy were nice to ... that jackson won in SlipX sig was nice to and definately Ike-Byrd and Foreman-frazier/norton The punch Hearns landed on Duran was brutal. The one that's in my mind right now is the left hook that Wilson landed on Nwodo. I mean that punch probably could be heard around the arena they were in.

Im sorry when you can hear the thud over the crowd.Then Im sure you got hit fuckin hard.

byrd knocked out cold by ike

thats one of the things that made holmes a legend, his iron chin Larry Holmes excelled at turning his head with the punch before impact, so he wouldn't endure the full force of the blow. Oscar does a decent job of it too. Just watch the Trinidad fight (in the 8th or 9th round) when Trinidad clocks him with a big right twice in a row, and Oscar just smiles at him...

My vote has to go to ike vs bryd................what a left uppercut. Agree. Insanely wicked punch!

ya Hearns-DURAN!!! Tito-Vargas and Joppy were nice to ... that jackson won in SlipX sig was nice to and definately Ike-Byrd and Foreman-frazier/norton

the Prince was one of the most brutal punchers I've ever seen. It's the kinda punch where it leaves the guy still standing on his feet but is already unconscious so they take some more dangerous blows. yeah man, speed kills sanders style

Ike-BYrd or even Tyson-Etienne, in that fight the way Etienne's knees jsut fell out fropm under him made it look like he got hit with a brick.

Dokes knocking out Gardner in the fourth round.

Hopkins KO Tito (Massive overhand right)

It wasnt the hardest punch ive ever seen but all the others have been takin.....Trinidad-Vargas that 12th rd left hook that but Vargas down the 1st time. i swear i thought i felt that punch at home

Spinks-Johnson and Laporte-Lockridge

Man, i don't know. There's a couple that i could pick out from some of Tysons fights. But, there's one with Verda vs. Ward (a woman boxing match) where Ward freakin levels verda. It's an amazing looking punch.

Tyson Any hit by Tyson in his prime was pretty hard.

My vote has to go to ike vs bryd................what a left uppercut.

the left-uppercut thrown by pacquaio on fahsan 3k battery it was nasty... so nasty that the thai fighter was literally "lifted" on both feet

lewis rahman 1... lewis smiled at rahman b4 he was caught by a wicked rahman punch...

The first knockdown of the Tyson Holmes fight. What a right hand!!

I too used to live in Sanfrancisco and people thought i was Somoan. Tua is just a puncher nothing else.
