TooFab has edited this article to reflect that "Dancing with the Stars" pro Lindsey Jordan injured her knee during rehearsal, not violinist and contestant Lindsey Stirling, as previously reported, based on a People article, which has been taken down. Read on to find out what happened, in the words of Jordan herself.

Lindsay Arnold suffered a knee injury during rehearsal Sunday morning that may impact her ability to perform on Monday's live semi-final episode. She is paired with this season's front-runner Jordan Fisher.

The injury occurred while she was performing a number with the dance troupe. Contestants often perform elaborate numbers with the troupe to open the live shows, and with next week's finale looming there are even more and larger numbers to learn.

"I was practicing the pro number and I literally just stepped up onto a stair and it felt like my whole leg gave out and stopped working and I thought it was just a one-time thing and then it happened a couple more times, just doing simple things," Jordan said in an exclusive video to People.

The remaining five couples will be performing two dances this week, with one of those a classic dance performed prior on the show.

Lindsay and her partner Jordan Fisher are the current front-runners on the show, having racked up an impressive number of perfect scores, including two of them last week. Professional dancer Sharna Burgess has been learning Arnold's part in case she is unable to perform.

"It’s frustrating because it’s the semi finals and I want to dance it with Jordan, and I just hope this doesn’t stop me from doing that," Jordan said. Either way, she will surely be on hand for the "Dancing With the Stars" semifinals, Monday at 8 p.m. ET on ABC.

Correction: An earlier version of this story incorrectly identified the injured dancer as contestant Lindsey Stirling. TooFab regrets the error.
