Top WWE Star Says He Entered Rehab Last Year - Details

In a shocking revelation, Rey Mysterio reveals in his newly released autobiography, Rey Mysterio: Behind the Mask, that he checked himself into a drug rehabilitation center last year as a result of a persistent issue with legal pain medication. It was due to lingering problems he had with his biceps last year.

If you recall, Mysterio suffered a biceps injury during an overseas tour in February and underwent three surgeries within the space of a month to correct the problem.
