Sally lasted a bit longer than Ola in the training, but still had to pull out before filming had even begun.

Tina Hobley - Series 3 (2016)(08 of15)
Open Image ModalWhat happened?
Despite two pre-series incidents, the second run of 'The Jump' managed to see all of its contestants clinging on without having to withdraw due to injury.
The same cannot be said of the third series, of which Tina Hobley was the first casualty, when she injured her shoulder and knee, as well as breaking her arm in two places.
She later claimed that her injuries cost her a potential role on 'Broadchurch', adding: "I couldn’t make it because I was in plaster. I’d been waiting two years for that job."

The then-reigning Miss GB was initially brought in by producers as a potential replacement for Beth Tweddle.
However, less than 48 hours after touching down in Austria, she was sent packing, with producers deciding they didn't think she could take part in the competition.
She later cropped up in 'Love Island', a move which changed her career, as her on-screen escapades saw her dethroned.

Linford Christie - Series 3 (2016)(12 of15)
Open Image ModalWhat happened?
Seriously, though. It was a bad two weeks.
Linford Christie was the next celebrity to pull out, as he suffered a hamstring injury, and wasn't left with enough time to recuperate and be back on the slopes before that week's live show.
Replaced by?
By this point, the stand-by contestants were all already on the show, so the previously-eliminated James 'Arg' Argent was brought back (only to then be swiftly kicked off again). (credit:Channel 4)
Sarah Harding - Series 3 (2016)(13 of15)
Open Image ModalWhat happened?
Remarkably, the show managed to go a whole week without anybody having to pull out.
Sadly, Sarah was the next unlucky celebrity who had to leave, after an accident left her with torn ligaments in her knees.
She later blamed the 'toll' of the incident when her performance in 'Ghost: The Musical' was critically panned later that year.
