Yah, I do agree that they were both out temporarily, but I think many people that get knocked down go out for even a split second, hence why they get knocked down in the first place. You see it in the UFC too where a fighters eyes roll back for a split second then they pop back in to it.
If we are going to DQ fighters that go out, we would need to get really specific, put time limits in place on how long they can be unconscious and find ways to measure their consciousness, as perceptions can be off....it just all gets very murky and the ten count is so much easier. I also agree there is no rule that says if the lights get switched off you must end the fight. The ref for that fight said giving the ten count was the greatest call of his entire career. Fury was more alert after that knock down than he was in the 3rd fight o the second knock down where he lost his balance.
