From main board:
WWE sources indicate that Luis Ignascio Urive Alvirde, the original Sin Cara, was sent home from Tuesday's SmackDown taping in Calgary, Alberta, Canada. He left the Scotiabank Saddledome before the event's conclusion.
Company sources state that developmental talent Jorge Arias (a/k/a Hunico) will exclusively portray the Sin Cara character going forward. WWE wants to maintain the character since its been very popular among kids and in merchandise sales.
Many employees expect Alvirde to part ways with the organization, but it is not 100% confirmed
Well that explains some of it I suppose but I'm very surprised by this turn of events!! Plus I bet HHH is pissed!!
