Tweddle was the first female gymnast from Great Britain to win a medal at the European Championships, World Championships and Olympic Games.
She retired in August 2013 and starred in ITV’s ‘Dancing on Ice’ before taking part in The Jump.
The reality show, which first aired in 2014 with twelve contestants, saw celebrities take on challenges like speed skating and ski-jumping.
But over the course of the four series, 34 contestants, including actress Tina Hobley and Strictly Come Dancing star Ola Jordan, sustained injuries.
During the same series that Tweddle was injured in, Girls Aloud star Sarah Harding was also forced to pull out due to a ruptured ligament in her knee.
