Just to clarify everything, Bryans problem is concussion related stemming from his match with Sheamus on the Smackdown tapings right after Mania. Many people in wrestling have known this for some time and we were told it as soon as he got sent home from the European tour. For whatever reason, at that point a bunch of denials were made because evidently WWE wanted that under wraps. The issue is career threatening at this point.

That sinking feeling in my gut, the one that says I might have been there in the O2 to witness his last ever wrestling match: getting stronger.
