Too many to mention, one of my faves is Juan Manuel Marquez, he gets put on his ass a lot and hops right back up and recovers impressively. I'll never forget the slow-mo of him leaping onto the ringpost with his nose pulverized and face all bashed up from manny's vicious assault, swallowing his own blood and legs shaking and most likely nose broken, stays in the pocket to wait for that insanely timed counter in the last second of the round, that takes some ****ing guts when the Pacman is a round from stopping you. Obviously that's the highlight of this whole era of the sport but just one example of Dinamita's resilience. That is the price of knocking manny pacquiao out http://www.abload.de/img/marquez4rree.gif
Have to give props to the Dark Destroyer ..What he survived in the fight with Gman proves his toughness
