He took "break a leg" a little too literally…
The country singer and ballroom dancer each shared the not-so-good knee news on social media Thursday, with Jana simply saying:
"This. Is. not. A. Happy. Photo. ;(."
Gleb elaborated about his temporary timeout a little more in his Instagram post, writing:
"Sorry @kramergirl for not being able to rehears with you today, hopefully my knee will be better and I can dance on Monday night @dancingabc thanks @alanbersten for standing in."
Is four days of rest really enough down time?!
Luckily, ABC has plenty of substitutes thanks to their Dance Troupe program — which means Jana will be joined by Alan Bersten for now as Gleb attempts to heal in time for Monday's episode.
Break a leg Good luck, Alan!
But more importantly… Get well soon, Gleb.
Ch-ch-check out Jana & Gleb's best dance of the season to remember the good ol' days (below)!!!
