Fights were boxers showed incredible heart

[SouthPawHitman]

In recent years it has to be Abraham fighting through a broke jaw. Also Paulie vs. Cotto

What other fights did guys show incredible heart and balls?

[SlySlickSmooth]

Mayweather when he fought Guerrero.

Mayweather when he fought Guerrero.

Especially the 12th round, he went toe to toe just like he said he would do

[El Angel]

Cotto when he fought Clottey.

Margarito wanting to finish his fight with Pacquiao even with his broken orbital bone is the one that sticks out the most to me. You could even tell Manny felt bad about fighting him and really wanted the ref to stop it. I was never a fan of Margarito but I still have to admire his spirit.

Bradley against Provodnikov is a more recent one. I was lucky enough to see that fight live, and I just couldn't believe how even after he went down, Tim refused to run against Provodnikov and instead kept exchanging with him. It was absolutely unbelievable to see.

I thought Amir Khan showed a ton of heart against Marcos Maidana. It's the fight that more than anything won me over on him. He survived a very tough opponent and came out on top. I think that fight still stands out as one of the high points of Khan's career.

another one: Lara when he fought Angulo. He got up from some rough knockdowns and never ran from Angulo, instead continuing to fight and engage him all the way until that fight was stopped. I think the guts he showed in that one was forgotten among people criticizing Angulo for quitting, it was a really good show of Lara's heart and determination.

Abraham has no heart and the only reason he fought on with a broken jaw is because he was gonna get the victory regardless. After that he had a history of complaining about low blows that weren't low, just constant bitchin' to the ref and going into a shell.

Mayweather when he fought Guerrero.

The fight in which Mayweather showed the most heart was against Carlos Hernandez at 130 where he went down officially for the first time because of the pain in his right hand I believe it was, he ended up messing up both his hands in that fight and still finishing the fight.

That is a good one, Maidana also showed great heart in that fight from getting up from that Body shot knock down, most guys would have stayed down. But he got up and survived the whole 12 rounds and putting a beatdown on Khan in the last 3. Just a great fight from both Men.

I am going to say Trinidad against Wright because he was getting dominated in an almost humiliating way. Wright was not hurting him physically but he was hurting his pride and I think it was a different way of showing heart considering how discouraging that fight was.

[Enzo Mc is SHIT]

Danny Williams dislocating his shoulder, fighting one handed and knocking his opponent the **** out is clearly the best example. Nothing else comes close.
