Del Rio has had some talks with TNA, which had wanted him as soon as he got his WWE release, and has told him that they will make him the top star of the promotion if he comes in. However, he would have to be released from Lucha Underground before doing so. Also, New Japan Pro Wrestling has interest in him as they believe he can be a top headliner for them.
Ever since he left WWE, the company has wanted him back. WWE never wanted him to leave in the first place as he was told by Triple H to just take the six months off and let things die down after he slapped an employee after the employee made racist remarks towards him at catering.
Del Rio was told he’d be brought back in six months, but that never happened. It’s said that a lot of WWE talents liked Del Rio and would like to see him comeback.
It is true that Del Rio and WWE have had talks about a potential return, but they have not reached a deal as of this writing.
