It sounds like old news, but the WWE just announced the release of the original Sin Cara from his WWE contract. According to Rajah.com on March 27, the WWE announced the release under his real name of Luis Ignacio Urive Alvirde.
It appears that the final date for the original Sin Cara on his WWE contract was March 26. Most wrestlers have a 90-day no-compete clause, which means he will not be able to appear on a television show for a competing company until June.
Sin Cara is signed with AAA wrestling out of Mexico and that group has a deal to broadcast their wrestling on Robert Rodriguez's El Rey Network.
The timing of the release announcement is also interesting because it comes just two days after the original Sin Cara came out on Twitter and called out the WWE for "fraud."
On "WWE Monday Night Raw" this week, their version of Sin Cara came out with Scooby Doo and beat Damien Sandow in a match. The WWE version of Sin Cara is Hunico in a mask.
There are currently legal battles ongoing between the WWE and Luis Ignacio Urive Alvirde about the use of the character of Sin Cara. Alvirde claims he owns the rights to the look and the character while the WWE claim they own the rights.
