Graham Bell will no longer compete inthis weekend after his skating partner was injured in training.
Former Olympic skier Bell, 55, and his partner pro skater Yebin Mok were involved in a "freak accident" which resulted in her leg being lacerated from a stab wound caused by an ice blade.
Mok received "immediate medical attention" and is resting and healing, ITV said, and Bell will skate alone in the group number on Sunday's show.
Rufus Hound and his partner Robin Johnstone, who were due to dance next week, will instead compete in Bell's place and Bell will skate as part of the second group of six celebrities taking to the ice on January 24.
He will partner with Karina Manta, who will step in for Mok.
Speaking on ITV's, Phillip Schofield said the accident was "proof now that really is the most dangerous show".
Holly Willoughby added: "This week Olympic skier Graham Bell and his partner Yebin had a freak accident which resulted in her having a laceration in her leg."
"It is a dangerous show, she's going to be out of the show for quite a few weeks I think."
- Dancing On Ice begins on ITV on Saturday.
