Former Olympic gymnast Beth Tweddle has undergone surgery to fuse fractured vertebrae following an accident in training for a reality TV show.
Tweddle, who won bronze in the uneven bars at London 2012, is competing in The Jump - a winter sports game show for UK broadcaster Channel 4.
The 30-year-old sustained the serious injury in training on Saturday before doctors operated on Sunday, using a piece of bone from her hip to correct the issue.
"The early medical indications were positive as Beth was able to move her hands and feet, despite being in a lot of discomfort," Tweddle's parents said in a statement on her official website.
"The medical staff have been fantastic and explained to us that Beth was waiting for an operation as there were more serious cases ahead of her.
"At 20:00 GMT last night Beth was taken down for surgery where they took a piece of bone from her hip and used it to fuse the two vertebrae that were fractured, along with pinning them together.
"It was a scary time for all of us and we're just very grateful that the operation was a success."
Tweddle herself commented: "Thank you so much for your support and concern. The last 48 hours have been very scary but all the messages have really helped to keep me positive. I will keep you updated on my progress."
Olympic swimming champion Rebecca Adlington had already pulled out after dislocating her shoulder, while actresses Tina Hobley and Louisa Lytton have also picked up injuries on the show, which is only two episodes into a series of six.
