Dancing with the Stars professional dancer Maksim Chmerkovskiy shared on social media a photo of himself in his hospital bed before undergoing surgery to repair a calf injury. "Gettin' unbroken," the 37-year-old dancer captioned an Instagram photo of him smiling, while wearing a hospital gown and with an intravenous line coming out of his hand. Us Weekly said the performer was hurt during rehearsals with his partner, "Glee" alum Heather Morris, last Friday. He did not compete on this week's edition of the competition series. "Dancing with the Stars" troupe member Alan Bersten danced with Morris in his place. It is unclear when Chmerkovskiy will return to "Dancing with the Stars," which is now in its 24th season.
