Dancing On Ice star Anthea Turner is recovering after hurting a rib during training for the ITV show.
The 52-year-old presenter said her on-screen partner, Canadian pro skater Andy Buchanan, spotted the problem, telling fans on Twitter: "Lying on my bed with Hot-water bottle strapped to my ribcage. @AndyBuchananTV felt it and heard 1 ping Y/day PAIN!!!!"
Anthea is on the hit show with other celebrities including rugby player Gareth Thomas, Olympian Beth Tweddle and Coronation Street star Samia Ghadie.
Last week, she said her stint on the show was worth all the injuries because it had given her "the best bum I've ever had".
She told ITV1's Lorraine show: "The toning of the body - ice skating - it's skater bum, it's amazing. I don't care even if I crash out on Sunday, I have had three months of the best bum I've ever had since I was somewhere in my 20s. In fact, even in my 20s it probably wasn't this good."
Sunday's show sees each pair go up against the duo who most closely matched their scores in the first round.
After each duel, one couple will receive immunity from the judging panel, leaving five celebs to face the viewer vote.
Former EastEnders actor Matt Lapinskas and professional partner Brianne Delcourt will compete against rugby star Gareth Thomas and Robin Johnstone, while politician Oona King and Mark Hanretty will face Olympian Beth Tweddle and Dan Whiston.
Corrie star Samia Ghadie and Sylvain Longchambon will face boxer Luke Campbell and Jenna Smith, while TV personality Keith Chegwin and Olga Sharutenko are up against funnyman Joe Pasquale and Vicky Ogden.
