Rey Mysterio to appear at AAA Guerra de Titanes in Guadalajara

Rey Mysterio will appear at Lucha Libre AAA Worldwide’s Guerra de Titanes on December 20 at Arena Guadalajara, the promotion announced during its Heroes Inmortales show. AAA said in a social media post that tickets go on sale October 31 through Superboletos, and the Hall of Famer confirmed in a prerecorded video that he will be in attendance.

The announcement marks Mysterio’s most prominent public involvement with AAA since he suffered a torn groin injury in April and stepped away from in-ring competition. Officials have not said whether Mysterio will wrestle at Guerra de Titanes. Industry reports indicate he has resumed training at WWE’s Performance Center in Orlando, but no official medical clearance or timetable for a competitive return has been released.

AAA revealed the date and venue during Heroes Inmortales, where Mysterio also appeared in the event’s cold open video. The promotion’s social post read, in part, "GuerraDeTitanes ya tiene fecha y sede 20 de Diciembre, Arena Guadalajara. Boletos a la venta 31 de Octubre por Superboletos." At the same show, Dominik Mysterio, Rey’s son and a WWE performer, retained the AAA Mega Championship by defeating Dragon Lee in the main event.
