Smart decision by Vitali, he had enough injuries already no need to add to it. If he had continued he wouldn't still be HW champion today. Jeff Lacy continued in a fight with that injury and we all know what happened to him.
Vitali was afraid of being stopped by Byrd, the guy who couldn't knock out a fly? The same Vitali who stood toe-to-toe with Lewis, trading dozens of shots without hitting the canvas?
You don't walk out of the ring with your title by winning the "event". I hope you're being sarcastic...
vitali fans: he was smart for quitting, disgracing himself and ruining any chance for being labeled great. real boxing fans: he punked out against a guy he could have jabbed, tied up, leaned on and won the decision and being held in the highest regard.
