Well, if that is true and he just took a Vitamin Shoppe supplement, I would be surprised that the WWE just didn't tell him to knock it off in private. This is a big blow to him and them as well. His push has been derailed after all the promotion they put into him and I imagine the locker room would be a bit pissed if he was given the belt back immediately upon his return.
I wonder if we will ever know, surprised we haven't by now.
