The Olympic gymnast crashed into a barrier after successfully completing her jump.
After just two weeks, several stars have already ended up in hospital after competing on the Channel 4 show.
Some fans have even taken to social media to ask for the show to be cancelled because they say too many people are getting hurt.
The Olympic gymnast suffered an injury to two bones in her neck but has had surgery.
Her parents say early medical indications have been positive and that she's been able to "move her hands and feet."
She is the third competitor to leave the show because of injury.
Olympic swimmer, Rebecca Adlington was the first to leave the show, after dislocating her shoulder.
Actress, Tina Hobley dropped out next after she injured her elbow and fractured her arm.
A Channel 4 spokesperson told Newsround:
"The Jump is now in its third series and since launch 46 celebrities have taken part successfully. Though it is a new course the events have been designed to be no more difficult than in previous years and all contributors have undertaken a rigorous training programme to prepare them for the show.  All winter sports carry some element of risk but  in light of the number of injuries this year,  Channel 4 has asked the producers to review safety procedures again to further reduce the prospect of accident."
