The Jump has reinforced its reputation as the most dangerous show on television after former Girls Aloud member Sarah Harding became the sixth celebrity contestant to pull out after being injured.
The singer and actress said she was forced to withdraw from the Channel 4 ski competition after suffering a ruptured ligament in her leg.
Harding took to Twitter to reject claims that she had quit the show, which involves a selection of winter sports activities including ski jumping and speed-skating, in Austria.
The 34-year-old said she was “gutted” to be told she could not continue in the show after six weeks of training but was proud to “make it this far ... despite the ups and downs”.
Earlier this month, Channel 4 began an urgent review of safety on the show after just two episodes had been broadcast.
The review was sparked by the hospitalisation of Olympic gymnast Beth Tweddle, who had surgery to fuse fractured vertebrae following an accident during training.
Former Olympic champion swimmer Rebecca Adlington, 27, withdrew from the show on medical advice after a shoulder injury.
She told the host, Davina McCall, that the pain of the fall was “the worst thing that has ever happened to me, it was worse than childbirth”.
Holby City actor Tina Hobley, 44, also departed after dislocating her elbow and suffering two fractures to her arm.
Made In Chelsea cast member Mark-Francis Vandelli, 26, left after fracturing his ankle, while sprinter Linford Christie, 55, became the fifth celebrity to pull out after failing to recover in time from a hamstring injury.
Former England rugby player Ben Cohen, 37, who was drafted in after contestants were forced to drop out, was also injured in an accident in which he lost two teeth and needed 20 stitches. Despite the injuries he will remain in the competition.
