Things got pretty ugly between AAA and Myzteziz, who was the original Sin Cara in WWE. Apparently, the masked performer had some backstage heat with Alberto Del Rio, who reportedly threatened a physical assault. The man legally known as Luis Ignacio Urive Alvirde showed up unannounced in CMLL and said that he wanted to return to that promotion. When his current employer found out, a release was immediately given.
