Time it. He doesn't wave the fight off until exactly at the end of the fight and the horn failed to sound. What are the rules for waving off a fight after the fight and not just a round Like Machida/Thiago Silva? There was a fight exactly like this at one time where it wasn't called a KO unless I'm mistaken. The final strike was thrown at 4:56, yes, but you absolutely cannot say that if the ref said "Keep fighting" and Rozenstruik turned back around that ANYTHING could have happened. There's a difference between INITIATING an attack with 4 seconds left and CONTINUING an attack on a fighter who has already been taking shots. There was no time. Askren was out before 5 seconds, but that's when the ref stopped it. Aldo was out before 13 seconds, but that's when the ref stopped it. How could the time have expired but call the fight 4 seconds before it actually happened?
