If the wrestler's name can be released by the coach, as it has been in this case, what is to stop him from releasing the doctor's name?

The doctor has a responsibility to diagnose patients correctly--if a business sells bad meat, the name of the business is released. If a company hires illegal workers, the name of the company is released. If a doctor is endangering public health, their name should be released.

Finally, the name of the wrestler does not even have to be released in this case. One can simply name the doctor who performed the incorrect diagnosis and keep the wrestler's identity completely anonymous.

While I usually respect your opinion, I would like to know the statute to which you are referring.
