Wikipedia says that AJ Lee has a "neck injury" that's keeping her out of action. As well, she's married to an MMA-fighting ex-WWE champion that's not-so well-liked by the company, too. Maybe it's possible she doesn't really have a "neck injury," then... However, AJ's still under contract, which wouldn't put her sprinting down to ringside and beating down the Bella Twins in order to set up a match between Nikki and AJ at Wrestlemania. Of course, if WWE could get AJ back for Wrestlemania, getting AJ to (once again) do the post-Wrestlemania favors (except this time in a longer feud) with Charlotte would be fantastic.
