Gleb Savchenko, Jana Kramer's partner on Dancing With the Stars, has injured his knee and is unable to practice.

On Thursday (Nov. 3), Kramer revealed the news via Snapchat; ET has screenshots of Kramer's two snaps, the first showing Savchenko on a doctor's exam table, and the second showing "the new Gleb," aka DWTS troupe member Alan Bersten.

"This. Is. Not. A. Happy. Photo." Kramer writes on Instagram, along with a photo of Bersten and herself standing beside the injured Savchenko, who is seated and has his right knee in a brace. On his Instagram account, Savchenko shared the same photo and wrote, "Sorry @kramergirl for not being able to rehears [sic] with you today."

Kramer herself sustained an injury earlier in the Dancing With the Stars season: During her first performance on the TV dancing competition, Kramer sprained her intercostal muscle, a muscle in her rib cage.

Dancing With the Stars airs Mondays on ABC. Savchenko is hopeful that he will be able to perform come the next show (Nov. 7).

In her music career, Kramer’s current single is the song “Circles;” the tune appears on her newest album, Thirty One, and is the follow-up single to her hit “I Got the Boy.” Personally, however, the past couple of months have been rough for Kramer: She and husband Michael Caussin separated in late August, and Kramer recently revealed that he cheated on her. Kramer also recently opened up about the abusive relationship she had with her first husband, Michael Gambino, who nearly killed her.

Kramer follows in the footsteps of fellow country stars Wynonna Judd, Kellie PicklerChuck WicksSara Evans and Billy Ray Cyrus, all of whom have previously competed on Dancing With the Stars. Fans can vote for Kramer and Savchenko on the TV dancing competition’s official website.
