Peta Murgatroyd has left the ballroom, everyone. On Tuesday it was confirmed that the blond-haired fan favorite would be sitting out of Season 21 of “Dancing With the Stars." And as it turns out, the news was just as a surprising to Murgatroyd as it was to fans.

Murgatroyd, who first joined the hit ABC series as a troupe member in 2011, initially confirmed in August that she would be partaking in the upcoming installment of “DWTS.” However, the 29-year-old stunner was recently forced to hang up her dancing shoes after encountering an injury.

During an interview with People magazine, the shimmying star revealed that her orthopedic surgeon told her she would need to undergo an operation. The surgery means that she would be unable to compete in Season 21, leaving one celeb without a partner. Although the dancing couples aren't supposed to be revealed until Sept. 2, Murgatroyd dished that she was going to be tangoing with “Honey, I’m Good" singer Andy Grammer.

“It was devastating news for me,” Murgatroyd continued. “I got my MRI results back and it was a really bad diagnosis.”

According to the dancer, she has four torn ligaments and a floating piece of bone at the back of her ankle. “My doctor said I need surgery and I knew I needed to put my health first it I want to keeping dancing on the show into my 30s,” she shared.

Although Murgatroyd’s surgery is scheduled for mid-September, that won’t stop this determined dame from finding a way to partake in the exciting, new season. That Season 14 winner explained that she wants to sit in during rehearsals to help out, like Derek Hough did when he was injured during Season 20.

During the show’s 10-year anniversary installment, Hough not only broke his toe during what he described as a “fluke accident” but also rolled his ankle while trying to get ice for his injury.

“To do something like that, so silly and so ridiculous, is just incredibly frustrating. I felt like an idiot,” Hough wrote in a blog post for TV Guide in April 2015. “One of my friends said to me, ‘Maybe this is just God saying, 'Hey, you need to put your feet up, both of them.’ But for me, I hate that idea.”

And apparently he’s not the only “DWTS” pro that despises the notion of sitting still.

"I'm just looking forward to being back on my feet as soon as possible and being a part of the show again," Murgatroyd said. "It's super frustrating but I'm going to fine and I'm going to be back in week eight or nine of the show."

The dancer then went on to console fans on Twitter who were heartbroken to hear she wouldn’t be competing.

“I will be back soon,” she promised. “Thank you xo.”

“Dancing With the Stars” will reveal who Grammer’s new partner is on Wednesday, Sept. 2, when the entire celebrity roster is revealed. Season 21 of the hit ABC series will then air on Monday, Sept. 14.
