I agree, I have seen a few times now where it looks like Tarver is ready to go. Not necessarily because he was hurt, but because he gasses so bad. I even felt like Roy had a couple chances to get him out of there in the 3rd fight, but just failed to let his hands go.
and in other breaking news the atari 2600 is due for release circa 1985! he was never a ko artist and it is in the last 6 years that he has fought way better competition!
