The doctors and their opinions.

Last night the doctor told referee Joe Cortez that Markus Beyer was unable to continue fighting, so the fight ended in a technical draw. After the bout was over that very doctor was being interviewed, and he said he had the impression the clash of heads was not accidental but intentional. Should, may, a doctor say somehing like that? He is the one that can advise the referee to stop a fight and declare a particular winner. Shouldn't he appear to be as unbiased, as objective as possible and only concentrate on a professional analysis of the injury?
