I read a rumour online that Sin Cara has been suspended for 30 days for ********* the Wellness Policy and that is why he was so quickly removed from the MitB match last night. Funny, I assumed it was because coordinating such a big match with a guy who can't speak English would be difficult.
He has been suspended for testing positive for anabolic steroids and WWE has known about this since early June. Word is that he may not even be brought back once his suspension is lifted.
