The ref totally ignored Choco's complaint about being head-butted. Strange since refs are supposed to at least acknowledge when such serious fouls are inflicted. In fact, I have seen some refs even halt the action and ask the injured fighter if he is OK to continue immediately. So it comes across as extremely strange to observe a ref purposefully going out of his way to convey that kind of callous attitude towards a fighter. Wonder what was motivating him.
Jesus ****ing Christ, how many excuses are you Chocolatito fanboys going to come up with? It wasn't a foul, much less a serious one, it was unintentional, therefore you can't call it one, that tends to happen when orthodox and southpaws fights especially when they're bot ridiculously aggressive like these two. He wasn't injured in the least, Abie Han was injured.
The ref calls the headbutts, not the fighters. Imagine if all it takes for the ref to stop the action is one of the fighters complaining about a headbutt.
intentionality or unintentionality are irrelevant to ref responsibility when a fighter is fouled and complains about it. So your premise is seriously flawed. BTW I am not a Choco fan and couldn't care less if he won lost or even drops dead.
Do you enjoy being ignored when you speak to someone in authority over you? I am not saying that he should have stopped the action. But totally ignoring a fighter is wrong and that is exactly what he tried to do. People who say that a head-but is no big thing are usually people who have never had a skull rammed into their face or have never had a skull to skull collission. The only way to describe it is sheer almost unbearable blinding agony. To have a ref turn his smug face the other way when a fighter points it out is simply inexcusable. Makes one wonder whether he has a stake in the fight's outcome. BTW This ref knew full well that Choco had been savaged by head-butts in the previous fights with no point deductions being levied. So he knew full-well why Choco was concerned about a possible repeat.
