-- WWE has lost a lot of faith in Sin Cara in recent months. He came into the company with a lot of hype and potential, but the masked star simply has not connected with the audience like management had hoped. His merchandise moves decently, but he's certainly not a big draw. His partnership with Rey Mysterio also did not springboard his popularity as expected.
-- While John Cena is definitely injured and banged up, the belief is that he will be able to work Extreme Rules 2013 in a WWE Heavyweight Championship match against Ryback. The company has been promoting the injury because they're wanting to sell the fact that their star performer is willing to work through injuries for the sake of the fans. As noted earler, WWE is expected to know more about the injury today when Cena undergoes further testing.
