UPDATE: Nikki Bella told TMZ Sports that the cyst on her brain is benign.
While appearing on last night's episode of The Tonight Show with Jimmy Fallon, Nikki Bella discussed the injuries that forced her to retire from professional wrestling.
"I really wanted to go back and fight for the [Women's] tag titles," Nikki said. "You know, I've always had my neck issues. And after neck surgery, like, it hasn't been okay.
"I felt like I needed to get that check-up before we went back for the tag titles. And then it came back -- I herniated the disc above where I had surgery. I have all this inflammation around the metal, and then I have a cyst on my brain. So they were like, 'You're done, no more, you're out.' So, I didn't get a choice."
Nikki & Brie Bella both announced their retirements from in-ring competition on season four of Total Bellas. They confirmed on The Tonight Show that Total Bellas will be returning for season five.
