I think the referee in a documentary on Tyson-Douglas, admitted that he was so inspired by Douglas's performance against Tyson, he treated him like his own Son and was determined to help Douglas up from that knock down. That is blattantly biased.
Actually Tyson got counted out faster. He lost 2-3 seconds going for that Mouth piece. He feared the ref would have waived the fight off if he didn't have his mouth peace by the time he got up. Secondly Tyson got up at 9.5-10, personally speaking to me, that is like getting up exactly in time though he had taken such a beating, i doubt he could have done anything more to survive.
