"It bothered him immediately, so we stopped. He walked off the floor. They immediately put him in a neck brace to hold it stable. They took him to the hospital and he had it checked. Luckily, there was no disk damage, no spine damage and no bone damage.
"We think he strained a muscle in the back of his neck, which is preventing him from turning his neck to the right. He's back and he is making jokes as usual. He'll be out there tonight standing with Shannon. He won't be dancing with Julianne and I tonight, sadly. Somehow we are going to make this work with the two of us. He will be good for next week," said Ballas.
You won't see Derek dancing on Tuesday night, but you will see him on the show.
