Nonsense, immediate rematch.
A man that has not only beaten, but demolished four former champions in a row does not need to get back into the mix.
He may have ran through Shogun, Rampage, Machida, and Rashad but if he loses it's most likely gonna be a stoppage since Hendo can only go for three rounds.
It'd be pretty hard to sell an immediate rematch if he ends up like Bisping and gets put on highlight reels until the end of time. If he could go in and beat down a guy like Glover provided he beats Rampage or squashes Forrest since he's coming off a win and hasn't got demolished by Jones yet, then he could get a rematch but whose to say that getting knocked out and knocked off his perch wouldn't drastically alter his career?
I doubt he loses but if he does, I don't see him getting an immediate rematch.
