cotto pac and adversity

i was re-watching a couple of cotto fights vs. torres, marg, and clottey 3 great fights in which cotto was really tested he was hurt bad against torres knocked down and cameback to win against marg he also showed alot of heart he took a lot of punishment and almost went 12 rnds. against clottey had a bad cut could of quit but did not and won a hard fought decision against a guy nobody looks good against even in the zab fight he had a very bad cut inside his mouth ...my question is besides the 1st. morales fight were pac was cut when has he had to comeback and fight thru adversity ex. came back after being knocked down or badly hurt ?...also could this play a part in their fight ? i know cotto can take alot of punishment can recover when hurt and has fought hurt and with bad cuts and shown heart can pac do the same ?
