What is the biggest display of heart in a boxing match?

[SlySlickSmooth]

Floyd Patterson went down SEVEN times before getting his title taken in the first match against Johnansson.

Fight should of been stopped earlier, Patterson didn't know where he was.

[Lester Tutor]

[NChristo]

Archie Moore vs Yvonne Durelle
Wilfredo Vazquez vs Antonio Avelar

[Fetta]

Recently

Berto/Soto Karass. He fought with a true shoulder injury for more than half the fight and almost pulled it off. That was pure heart

[NUCLEAR]

Pacquiao against margarito..

Those brutal liver punches from margarito should have made pacquiao to take a knee but pacquiao just shrugged it off and ignored the pain ,that fight made me realize that pac was really something else.

[Cobra_]

Froch/Groves I

Froch went down from a shot that would have KO'd most fighters, took a vicious beating for most of the fight. Came back and managed to get the stoppage.

Stoppage was bull**** but the comeback was incredible. Same with his fight against Taylor but the KD against Taylor was not close to being as heavy as the one against Groves.

[STAX ON DECK]

broner vs maidena <<<<<<<<

[chargerhemi06]

Pac s Morales 1. Pac knew he was losing and his face was cut up but fought his heart out until the very end.

[Motofan]

I'm sure its been mentioned, but "spinal."

[lx!!]

Erik Morales vs Pacquiao 1/ 12th round. That's what boxing is all about. We need more like him.

Hollyfield vs Bowe 1- Bowe landed some shots that should have put Hollyfield out for good, but kept coming.

Gomez vs Pintor- no need to explain this one.

Carbajal vs Gonzales

Motales vs Maidana- way past his prime in a weight class he didn't belong in against one of the biggest punchers everyone talked as if Morales would get killed. Yet he fought with one eye & did enough to win in the eyes of many to include people who doubted him. Lost officially, but didn't matter after the way he performed

To many to mention fughters always show courage & heart just stepping in there. Those are just some that stand out.
