Kem Cetinay's Dancing On Ice pro partner has reportedly been left injured ahead of tonight's show.
Skating pro Alex Murphy is said to have "badly damaged" her ankle during final rehearsals for Sunday night's episode.
As she recovers, it's left the pair's planned live performance in doubt.
Insiders told the Daily Star Sunday (via The Sun) that there was a '50 per chance' of Alex missing the show.
A reserve pro skater has been lined up although Kem and Alex may alternatively be given a pass to next week if she cannot skate.
A source explained: "This is a nightmare for Kem and Alex. They’d worked really hard on their routine for this week’s show but now everything is hanging in the balance.
"It’s 50/50 whether she’ll be able to perform.”
As things stand, eight celebrities are left in the competition which is now past the halfway point.
They'll all skate again tonight in a 'Love' themed week of performances.
At the end of each skate, judges Jayne Torvill, Christopher Dean, Jason Gardiner and Ashley Banjo will mark the celebs out of 10 before viewers vote for their favourite.
The two celebrities with the fewest combined judges' scores and viewer votes will then face off in the skate off where the judges will decide who to save.
Alongside Kem & Alex, the couples remaining on the Dancing On Ice cast are Donna Air and Mark Hanretty, Alex Beresford and Brianne Delcourt, Antony Cotton and Brandee Malto and Lemar and Melody Le Moal.
They're joined by Jake Quickenden and Vanessa Bauer, Max Evans and Ale Izquierdo and Hamish Gaman and Brooke Vincent and Matej Silecky.
Jake is currently the hot favourite to win after topping last week's scoreboard. Meanwhile, Lemar has been tipped to go next after surviving three skate offs to date.
Jessica Bridge of Ladbrokes said: "Lemar must have more lives than a cat and, although he's a worthy favourite to leave the show, he will probably make it through once again, leaving one of the better skaters to say goodbye."
Dancing On Ice 2018 continues Sunday night on ITV at 6PM.
