Katherine Jenkins' injury during her Dancing with the Stars salsa performance on Monday night with professional partner Mark Ballas as apparently turned out to be nothing serious.

"Morning all... Thanks for your tweets of support & concern. The good news is that I'm feeling better, just a little sore," Jenkins tweeted Tuesday.

The opera singer and fourteenth-season Dancing with the Stars contestant had previously tweeted doctors determined she had suffered a reflectorical spasm in her lower back during Monday night's semifinals performance show.

Ballas was concerned about his partner when she had to immediately stop dancing at the end of their second routine and he had to strive to hold her up. The pro dancer later apologized to the couple's fans for the interruption.

"Sry guys we couldn't finish R dance. Katherine hurt her back, I tried my best not let her fall at the end :) hope we still have ur votes," Ballas tweeted last night.

Jenkins and Ballas finished in fourth -- and last -- place on the judges' leaderboard with a grand total of 56 out of 60 points. The pair performed an initial quickstep routine which earned them 29 points from Dancing with the Stars judges Len Goodman, Carrie Ann Inaba and Bruno Tonioli and followed it with the salsa dance, where Jenkins' mishap occurred, that received 27 additional points.
