Sounds like his testing is not going well:
Jeff McLane@Jeff_McLane
RB: Sent McCoy to Pitts for further evaluation.
Still in Phase 4 of the concussion program, LeSean McCoy and Michael Vick have been ruled out for Week 14.McCoy was sent to the concussion center in Pittsburgh, which is never a good sign. He's been very tired at night and still has symptoms when active. Neither player has passed his ImPACT test, though both are taking it again on Friday. Vick is working out at a high level, but his reaction time is still an issue. We wouldn't expect either player to be available for Week 15.

From this, I ask this question of any Pittsburgh locals (or any other FBGs in the know): IIRC, Sidney Crosby was sent to a concussion specialist in Atlanta...Claude Giroux of the Flyers too. (Here is the article referring to the Atlanta doctor as being the go-to guy for hockey concussions:

I would assume that Crosby and Giroux left Pennsylvania and went to see the best, so why is McCoy going to Pittsburgh?? Can McCoy not fly??
