I really don't want to sound like a hater , is not my thing but this guy is garbage he's all flash, the guy is garbage , he's wild , inaccurate not that powerfull he has nothing, he looks tired and now too. He has been exposed here.
That ref should be banned for officiating, its not his job to call the fight because it is not winnable, that is the corner's decision, he is there to judge the fitness of the fighter and to keep order.
It had nothing to do with being in danger. He was taking punishment and not punching back. Gamboa was missing because Rojas kept his head basically near his knees.
