One of AJ's dirty tactics was an old style method....hit your opponents thigh; it can virtually paralyze him. The one obvious time it happened the ref stopped the bout and gave Usyk, who was obviously in pain, some time to recover. It was the only thing that ref did in a proactive fashion all night. I'm guess that his new old style trainer Garcia taught AJ that sneaky move.
I’m surprised AJ didn’t try to cheat more. The ref had blinders on to the many low blows he landed. Not to mention the hammer fist punch, one to the top of the head. It would have been nice to see Usyk retaliate and hit AJ below the belt or behind the head but he’s too classy for that. He beat AJ soundly, within the rules. Plus I’m sure the ref would have penalized Usyk if he threw the same low blows.
