It was reported  Sunday that Rey Mysterio is working through an injury to his rotator  cuff. He suffered the injury while working the SmackDown brand's most  recent tour overseas. Doctors advised him not to fly due to an inner ear  infection he was suffering from at the time but company officials asked  him to work the tour anyway, assuring him that wouldn't have to work  any matches. However, he was asked to wrestle while on tour, and  complied, only to suffer an injury to his rotator cuff. There was much  acrimony over the circumstances that led to the injury, to the point  that creative had no ideas for him when his feud with Alberto Del Rio  conclude.
Company officials tried make things up to Mysterio by allowing him to  handpick his next opponent, which turned out to be "Dashing" Cody  Rhodes. Current plans call for the storyline to continue through WrestleMania, with a likely encounter between the two.
Due to the injury, officials are limiting his in-ring work at television  and pay-per-view events, as well as house shows. He's contained in tag  matches when he does work non-televised events. Mysterio is said to be  hopeful that he can avoid surgery through rehabilitation.
