To be fair, you could never get a MD that was an expert in all possible injury/medical scenarios. This wasn't an injury with a bum knee or torn up shoulder, which is generally the type of problem that is typically thought of with sports medicine. Having said that, that is the very reason he, or any single physician in Tucker's position, should defer to the expertise of specialists, most of which wouldn't be considered sports medicine docs. A better set up would probably be to have a board of physicians that would include a cardiologist, neurologist, orthopedist, etc.
