40 years old.
missed 4 years because basically he kept injuring himself in training and decided to retire.
only 2 fights lost were when he tore a rotator cuff (Byrd) and when Lewis busted his eye up and it was stopped.

And he appeared to be fighting with a messed up left hand today.

How many 40 year old fighters that were injured alot, take 4 years off, come back, win every fight, and then wins against a much younger fighter with only one hand?

Is the HW division good? No, but Vitali just wins.

You can only fight your era.
