Jana Kramer and Gleb Savchenko spent the entirety of "Dancing With The Stars" season 23 delighting fans with a series of emotional --and in some cases, super sexy-- routines, but an untimely case of the flu could submarine the popular duo's chances of snagging the Mirrorball Trophy, according to Nov. 19 developments.

Gleb Savchenko out for 'DWTS' season 23 finale?

The "Circles" singer shared the unfortunate news via Twitter yesterday. She first posted an image of herself alongside a medical-masked Savchenko that featured the caption "One of us has the flu...well maybe two of us. @Gleb_Savchenko.

Excuse me while I go vitamin C overdose."

Three hours later, she posted a follow-up image. This time around, the photo featured a mask-wearing Kramer with "DWTS" season 23 troupe member Alan Bersten in Gleb Savchenko's usual place by her side. Since then, the singer and actress has been quiet on social media.

Although Savchenko's status for the "Dancing with the Stars" season 23 finale is up in the air --a source told People that his participation will be a "game day decision"-- there's a silver lining for Jana Kramer (assuming she's managed to avoid contracting the virus herself): she's danced with Bersten before.

The "So You Think You Can Dance" alum rehearsed with Kramer for the Nov. 7 live show after Savchenko sustained a knee injury. Although the latter rebounded to perform during ShowStoppers Night, Kramer is at least familiar with Bersten and his style, so all would not be lost if he had to step in during the finals.

Through the Nov. 14 semifinals, Kramer and Savchenko have earned a total of 408 judges' points from regulars Carrie Ann Inaba, Julianne Hough, Bruno Tonioli, Len Goodman, and a series of guest panelists. Two pairs --Olympian Laurie Hernandez and Valentin Chmerkovskiy, and IndyCar driver James Hinchcliffe and Sharna Burgess-- have earned more with 428 and 425, respectively, and one --former NFL star Calvin Johnson Jr.

and Lindsay Arnold-- has earned fewer (404).
