It might be some time before Derek Hough can dance again. The "Dancing With the Stars" pro, who was partnered with Olympian Shawn Johnson for the show's "All-Star" season, aggravated a pre-existing neck injury during the program's Oct. 30 broadcast.
"I have a bulging disc on my vertebrae," he explained to Us Weekly as he iced his neck post-show. "I've had it for a couple years. I need surgery on it. It flares up and it did today unfortunately. It immobilizes me but we dance through it on adrenaline."
The pain was too much to push through Monday night, however.
"Derek's injury is really serious," a show insider tells Us. (Mark Ballas filled in for him, instead).
In fact, the choreographer's condition is so severe, "It's likely Mark will finish out the season for him."
Adds the insider, "Derek is so disappointed but very badly hurt. He needs surgery."
Should Derek or Mark get the mirror ball trophy if Derek has to bow out and Shawn wins? Share your thoughts on our Facebook page.
