The fact that it was his sternum as well makes it all the more necessary a stoppage. In fact, these two injuries made a TKO very likely in the 3 remaining rounds, and Victor won't be fighting for a Very long while. Yes, boxing is a throwback to gladiatorial games. However, no athlete alive today is under any obligation to perform as a gladiator. (unless you're a slave in south-east asia) If Abraham and Malignaggi go above and beyond what's expected of them, then they deserve merit, but it's just that, beyond what's expected of them.
Like I said he should have given his corner and himself an opportunity to see if they can adjust and win that way, real fighters look for ways to win under these circumstances. For example Israel Vazquez who had his nose broke early in his first fight with Rafa Marquez, he went back got advice and fought on until he no longer could, that wasnt the case last night, as soon as it happened Victor quit. and He didnt just start quitting then, he was looking for a way out, he started fouling when he realize Lopez was much more than expected, blatantly hitting him to the back of his head like that. He wanted out as was the case with the Mayweather fight so is the same with the Lopez fight
people defending ortiz need to take a good look at themselves and there morals he grabbed the referee who himself thought he should continue, if fighters arent being robbed wasnt bad enough now we have a chronic quitter on our hands.
