Bruno Tonioli is set to miss this year's Strictly Come Dancing on BBC One.
The 64-year-old choreographer has decided to prioritise the US show Dancing With The Stars over the UK version amid the coronavirus pandemic.
A source told the Daily Star Sunday newspaper: "Travelling back and forth to the US isn't likely to be possible this year. The primary concern is that regular flights would put Bruno at risk of catching the virus.
"And on a logistical level he may need to quarantine every time he arrives back in Britain, which obviously isn't viable if he needs to be back in the US just a few days later."
On top of hat, Tonioli has been warned against making regular flights across the Atlantic, especially given his age.
The insider said: "Producers don't want to take any chances. Bruno's health is the priority."
As a result, Strictly will now be on the lookout for a new judge to work alongside Shirley Ballas, Motsi Mabuse and Craig Revel Horwood on the next run of the BBC show.
The source noted: "Bruno has missed weeks here and there in the past because of his commitments in the US, and other stars have covered for him.
"But finding someone to replace him for a whole series will be a big ask. Also, he is so popular. Without him some viewers may switch off."
