Nikki Bella could miss WrestleMania if she is forced to undergo surgery on her injured back. The former Divas Champion is suffering with a bulging disk, rumoured to have been caused by her Rack Attack finisher. Bella had an epidural shot earlier this week to help the problems and will continue to rehab, although the Wrestling Observer have reported that her recovery isn't going well. Nikki is scheduled to get an MRI at the end of the month to find out if she requires surgery. If she does, her spot at WrestleMania will need filling as she'll be out for a long time recovering. Although, the Observer speculates that her situation could be a little deceiving, with it being incorporated into her Total Divas storyline. This is the latest setback for the company after the news that both John Cena and The Ascension's Konnor are both set to miss a prolonged period in the ring. Cena, Nikki's partner of course, requires surgery on an injured shoulder, while former NXT Tag Team Champion Konnor dislocated his jaw during this week's Superstars taping. They join the likes of Seth Rollins, Randy Orton, Cesaro and Daniel Bryan on the shelf, injuries that have decimated the roster.
