#2. Rey Mysterio vacates the United States title
Rey Mysterio got sweet revenge at Money in the Bank when he defeated Samoa Joe in under two minutes to become United States Champion. He called his WrestleMania defeat to Samoa Joe (in under a minute), "the most humiliating loss" of his career.
It must have been satisfying to win the title, but he was immediately on the receiving end of a Samoa Joe beatdown - and we all know how that ends. Unfortunately, apart from just the fact that Joe's shoulders were clearly up when he got pinned, Rey Mysterio revealed that he suffered a seperated shoulder in the post-match beatdown.
As a result, he'll be coming out to vacate the United States Championship this week. Samoa Joe was naturally more than happy and he will expect to be crowned the new champion again.
Unfortunately for Joe, it doesn't work that way. We could either see a new champion as soon as tonight or a match for Jeddah to crown a new champion.
