He is a real tough guy. When he complains about pain it must be unbearable. In round nine Vitali tried very hard to knock out Byrd with a lucky punch. But he didn't succeed. Afterwards he could not even raise his arm for a clinch anymore.
Many athletes quit fights moaning.
Vitali stopped like a man. On Saturday I reproached myself that I didn't stop the fight two rounds earlier. Today, after reading the medical diagnosis I reproach myself for not stopping it three rounds earlier. This structure is responsible for raising and turning the arm. These movements were impossible from the point on where the injury happened.
