Longtime AAA ring announcer Arturo Rivera posted the following on Twitter @rudorivera:
"EXCLUSIVE !!! Alberto del Rio, former WWE wrestler, AAA integrates, and debuts this Sunday Triplemanía XXII. Welcome home, figure."
This will be Del Rio's first appearance since being fired by WWE last Thursday (8/7) for an incident with a WWE employee. AAA Triplemania XXII will be live on iPPV this Sunday evening opposite the WWE Summerslam PPV. AAA has yet to officially confirm Del Rio's appearance for Triplemania XXII as of this writing.
