Dave Meltzer reports that AAA did not have any kind of deal worked out with WWE to use the Sin Cara name. At this time it’s unknown if there are plans on WWE’s side to go after AAA or Sin Cara.
Regarding Sin Cara using that name in AAA last night at Guerra de Titanes, there was no deal worked out with him or WWE to be allowed to use the name. He was on a 90 day non-compete. We’ll see how this transpires.
This is a very interesting situation. If WWE doesn’t go after AAA and/or Sin Cara one might be led to believe this could open the door for repeat situations like this in the future.
