--Nikki Bella is the longest-reigning Divas Champion ever, as she surpassed AJ Lee's mark of 295 days. Sunday marks 301 days of Team Bella on top.

--There is a lot of buildup to the mystery partner for Dean Ambrose and Roman Reigns tonight. Such names as The Rock and Chris Jericho are rumored to be involved.
