Singer and actor Jason Donovan will be absent from Sunday's Dancing on Ice due to back pain.
Under the ITV show's rules, celebrities can miss one week of the show without being eliminated.
In a statement, Donovan said: "I've had back pain the past couple of days and I'm under doctor's orders to take it easy and sit this week out.
"I'm resting up, I'll be watching from home and cheering everyone on and I look forward to returning next week."
The Press Association reports that this year's show has been hit by withdrawals.
On Friday, Emmerdale star Joe-Warren Plant and his professional partner Vanessa Bauer became the fourth couple to quit the competition after they tested positive for coronavirus. Comedian Rufus Hound also left the show after he tested positive.
Reality TV star Billie Shepherd departed after sustaining an injury in a fall, while actress and singer Denise Van Outen withdrew after she partially dislocated her shoulder in training.
