Rey Mysterio is reportedly in the midst of a contract dispute with AAA over his contractual deal and the way in which they handle themselves from a business perspective, according to Pro Wrestling Sheets. 

The former WWE Superstar has not appeared on any of the company's recent shows due to money issues and shady business practices from his own perspective. 

Mysterio's deal with AAA was that he would be paid for date away from home, this could be TV, house shows or general media appearances. The issue seems to be that Mysterio is not being paid for all his appearances and he is unhappy with the current situation.

Mysterio last appeared for AAA in December.
