I know. Just watch the fight online. Has some interesting rounds and Vitali at times looks puzzled how to 'crack' that high guard.
I've seen the fight. That was an injured Vitali just coming off the Byrd loss fighting an undefeated Hoffmann (who has a heck of a chin) He won every round easily.
Vitali has an amazing chin, but he does not need it, as his defense is one of the best all-time at this weight.
