LOS ANGELES, Nov. 4 (UPI) -- Jana Kramer's Dancing with the Stars partner was injured Thursday.
The 32-year-old actress and singer rehearsed with Alan Bersten after partner Gleb Savchenko hurt his knee.
"This. Is. Not. A. Happy. Photo. ;(. @glebsavchenkoofficial @alanbersten @dancingabc #dwts," she captioned a photo on Instagram of Savchenko with a brace on his leg.
"Sorry @kramergirl for not being able to rehearse with you today, hopefully my knee will be better and I can dance on Monday night @dancingabc thanks @alanbersten for standing in," Savchenko wrote on his own account.
Sources told People Kramer is "running the routine" with Bersten but that Savchenko is "still going to rehearsals." The pair reportedly won't know until Monday if Savchenko will be able to dance on the live show.
"Doctors have advised Gleb to rest his knee," Dancing with the Stars said in a statement. "In the meantime, he is helping Jana as she continues to rehearse for Monday's show."
Dancing pro Sharna Burgess, who was partnered with race car driver James Hinchcliffe, was also sidelined with a knee injury this week. Her rep told Entertainment Tonight that doctors recommended that she not dance for three to six weeks.
Kramer and Savchenko had earned a 27 with their jazz routine to "Little Shop of Horrors" on Monday's Halloween-themed episode. The actress is known for playing Alex Dupre on One Tree Hill, and released her second studio album, Thirty One, in 2015.
