No, not crying wolf or the ref giving benefit of the doubt due to the context of the earlier low blows. Just context upholding Dubois’ primary intent to deliberately foul and him being guilty of low blow otherwise during the fight. Tbh, the ref actually ignored the fouls prior to but simply couldn’t ignore the most flagrant foul. When Dubois continued to foul after the fact of the officially ruled foul, even despite Usyk’s admonishing reactions, the ref did nothing. Definitely a perfectly placed and sufficiently powerful body shot can cripple the best of them - see Ken Norton’s absolutely clean left to Ali’s body in the rubber match - that punch almost did the trick but it was Ali after all and he recuperated very quickly.
