Fights where a fighter broke/injured their body and continued to the end

[Ahmed_Ismail]

Mayweather used to hurt his hand alnost everytime he fought when he was younger, i remember him breaking his left hand on the top of Carlos Hernandez's head in 2001 and the pain was so severe he had to take a knee, but then he got up and fought the rest of the fight with one hand, one of his toughest fights to date.

Even though it was through a mouthpiece and glove, Floyd fought through a badly bitten hand.
