8 "Ends Of An Era" At WWE WrestleMania 33
6. Nikki Bella's Retirement
If recent rumors are to be believed, Nikki Bella may be facing a retirement of her own. Fans of "Total Divas" saw the star struggle to return to the ring in 2016 after being put on the shelf with a neck issue the previous October, but apparently, she doesn't have a 100% clean bill of health. According to recent reports, Bella's neck is bothering her again, and she may have to put an end to her full-time in-ring career.
It's sad to see someone forced to put her career behind her without making the choice herself, but it looks like Bella will get to go out with a bang. Pencilled-in WrestleMania plans will see her team with real-life boyfriend John Cena against The Miz and his wife, Maryse.
After that, she might return in the future for major matches and programs - but her full-time career will be over.
