No, you are right. I think I got mixed up thinking post Rooney or post Douglas instead of post prison.
That was the fight ending knock down, which I agree was clunky, Lewis kind of shoves him after the punch. Mike clearly wasn't interested in continuing to fight by that point, so no one really makes a big deal of it. I was thinking of the earlier "knockdown" in the round. Ref calls it a knockdown and gives Mike a count, but its not clear if he went down. He gets hit and ducks real low to a squat. Maybe his glove or briefly knee touched? I didn't see it. Eddie Cotton did an overall poor job that fight.
