In a fight that was supposed to tell us if Oleksandr Gvozdyk had mentally recovered from almost killing Adonis Stevenson just a few months ago, Doudou Ngumbu's freak leg injury insured that we wouldn’t learn anything from the bout. Ngumbu was getting handily beaten, until in the fifth round he moved away from Gvodzyk along the ropes and collapsed in pain, grabbing his calf. The referee let him take a bit of time, but when he got up it was clear he couldn’t continue so the fight was stopped. Officially, Oleksandr Gvozdyk scored a fifth-round TKO to defend his WBC light heavyweight title.
