Ryan Tucker, right tackle for the Cleveland Browns is out for the season due to an undisclosed mental disorder.
I'm guessing it isn't anorexia nervosa, as common as that is amongst NFL linemen.
The Browns have made it clear that the disorder is common and not related to playing football. Which raises an interesting question--what rare mental illness is related to being an NFL player? I don't know. Pervasive guilt?
The Browns didn't explicity rule out Depression, which would be understandable, seeing as Tucker is playing for the Browns, which is, only in the most technical sense, playing professional football.
Whatever it is, I think we can rule out Fear of Success.
Godspeed, Ryan Tucker, get yourself better, and almost as important, get yourself out of fucking Cleveland.
