Former Brookside actress Jennifer Ellison was left bloodied and in shock after kicking the back of her head with a skate during 'Dancing On Ice'.
The 28-year-old was given medical treatment after the accident on last night's show.
Fitness guru Rosemary Conley was eliminated after admitting that the other competitors were "really raising their game".
Skier Chemmy Alcott was saved by all three judges following the skate-off.
Host Phillip Schofield told ITV1 viewers that Ellison had "a little bit of shock" after suffering her injury.
She appeared emotional in footage which showed her receiving medical treatment for a head wound.
Ellison's skating partner Daniel Whiston said the accident occurred as she attempted a kick.
"At the end of the routine Jen does a scorpion kick.
"She threw her leg really high and the heel of her skate has gone into the back of her head."
He added: "Her whole hair was just red because obviously the heart's pumping and a lot of blood's come out."
The professional ice-skater described her as a "trouper" and praised her for finishing the routine.
"Everyone cares about her very much, including me, so she will be OK," he said.
Ellison, who wore a sizzling red outfit for the Valentine's Day-themed show, was scored 19 out of 30 by the judges, but she was off-screen receiving treatment when the results were announced.
Robin Cousins revealed that his fellow judge Katarina Witt warned in rehearsals that "she's got to be careful".
He said: "As a dancer the last thing she would think about would be what's on the end of her boot.
"The other thing that people do forget is that the skates make your feet the heaviest part of your body so just doing a little bit of a flick certainly makes the whole thing go a lot harder."
Head coach Karen Barber said the incident demonstrated "how dangerous ice-skating is".
'Hollyoaks' star Jorgie Porter, with her partner Matt Evers, got the highest score from the judges for the second consecutive week.
They were awarded 26 for their dance to 'Fallin' by Alicia Keys.
Judge Louie Spence, who gave the pair the first nine of the series, said it "brought a tear to my eye".
He added: "You don't need experts when you see such beauty like that. Anybody can see that that is an absolutely stunning and beautiful performance.
"Every part of it - the emotion, the technique, the love - honestly it was absolutely beautiful."
Next best judges' score was 23, to singer Chico and his partner Jodeyne Higgins for their routine to Nat King Cole's 'L.O.V.E'.
Chico was so pleased with their performance he said it felt like winning the World Cup.
"When I picked up Jodeyne on my head I felt like Bobby Moore and she was my cup in 1966," he said.
Next week's show will feature the contestants dancing solo and being assessed for their technical skills. Two of the celebrities will leave the show.
