NS.. ex-NFL players sue league... It's starting to make sense now

Players do have the right to outside second opinions and the right to pick the surgeon they want if surgery is needed. This is spelled out in the CBA.

Correct. As I stated in my post, they can REQUEST to get a second opinion, but can't just go out on their OWN. They have to consult with the Team Doctor first.

Sorry I wasn't clear on that.
