From Bloody Elbow June 5, 2013
"After the fight against Alan Belcher, Michael Bisping completely lost all peripheral vision in his right eye. He went to see an eye on doctor on Tuesday and he found out that he had a detached retina. On Thursday, he had surgery to fix the detached retina. He's hoping to return to the UFC in October."
I think eye surgery has advanced since the days of Sugar Ray almost ended his career in 83. Here's hoping the Count has a full recovery.
