Jana Kramer and dance partner Gleb Savchenko will be fighting for the Dancing With the Stars Mirrorball Trophy on Monday night (Nov. 21), but in the days leading up to the Season 23 finale, they found themselves fighting something else: the flu.

On Saturday (Nov. 19), Kramer shared on Instagram a photo of herself and Savchenko in a rehearsal studio, with Savchenko wearing a surgical mask over his nose and mouth: "One of us has the flu ... well, maybe two of us," Kramer wrote. "Excuse me while I go Vitamin C overdose."

Later on Saturday, Kramer shared another photo -- and this time, she was the one wearing the surgical mask ... and Savchenko was nowhere to be seen.

"Im being quarantined with @alanbersten," Kramer explained. "Please feel better @glebsavchenkoofficial #flu"

Those fans who have been following Kramer and Savchenko's DWTS journey will recognize Bersten: He recently filled in for Savchenko during rehearsals when his knee was injured, and he joined Kramer and Savchenko for a trio dance during the semi-finals round.

Kramer and Savchenko haven't had it easy during their time on Dancing With the Stars. In addition to Savchenko's flu and knee injury, Kramer herself sustained an injury earlier in the season: During her first performance on the TV dancing competition, Kramer sprained her intercostal muscle, a muscle in her rib cage.

Kramer and Savchenko will be competing against James Hinchcliffe and Sharna Burgess, Calvin Johnson and Lindsay Arnold and Laurie Hernandez and Val Chmerkovskiy for the DWTS Mirrorball Trophy during the Dancing With the Stars Season 23 finale, which begins Monday at 8PM ET on ABC. Fans can vote for Kramer and Savchenko on the TV dancing competition’s official website.
