Alberto Del Rio is finished with WWE. According to sources close to the situation, Del Rio informed WWE through his lawyer that he was opting out 60 days ago.
Del Rio was apparently frustrated with the empty promises he was given after being recruited to the company last summer. Del Rio had been promised a main event push, but instead was quickly put into a Mex-America angle that went nowhere, followed by being bundled as part of the mid card heel faction, the League of Nations.
As noted, WWE announced on August 17th that Del Rio and his real-life girlfriend, Saraya-Jade Bevis, a.k.a. Paige, were both suspended for 30 days for their first violations of the company's Wellness Policy. The timing is interesting given that Del Rio had given his notice several weeks earlier, in late June.
Del Rio last wrestled for the company on the August 19th episode of SmackDown, where he faced John Cena. He is not expected to return to the company at all, and is free at the end of September to work anywhere in the United States. He will be able to work in Mexico and abroad imminently.
