Jacoby Jones and Karina Smirnoff were practicing a flip when something went wrong.
Smirnoff landed on the NFL pro Sunday, twisting her neck and banging her face, and she had to be taken to Cedars-Sinai Medical Center for possible whiplash and a dislocated jaw, a source tells PEOPLE.
She writes that “not dancing isn’t an option.”
Jones and Smirnoff are set to perform the Lindy hop.
One couple will be eliminated Tuesday, with the remaining four competing in next week’s finals.
