Craig was asked about the slip up and denied the rumor, saying "Why would I ever bother doing something like that? F-ing hell! Pffft. Play an extra in another movie?" Then he said, "Talk to Simon Pegg. He obviously knows way more than I do. He's just jealous because he's not in Star Wars. He's got some issue with J.J. I don't know what the f- it is. You need to talk to Simon about it."
Sources say this this is indeed true, so perhaps Craig was acting over the top with denial in order to throw everyone off. Look for Craig's cameo during a certain interrogation scene towards the end of the film.
