In tonight’s show, 12 strong and sexy singles enter The Lodge for the ultimate battle of the sexes.
Arriving on two separate safari jeeps, a Girl and a Boy from each team on the cast get dropped off and are faced with a walk over a bridge across The Waterhole to The Lodge.
However during the first Girls v Boys challenge, Dani hurt her arm.
She's since been forced to leave the show after medical intervention.
A spokesperson for ITV said: "Dani injured her shoulder during the recording of a challenge.
"She was attended to by on site medics and taken to hospital as a precautionary measure.
"As Survival Of The Fittest involves physical challenges which she wouldn't be able to take part in, Dani isn't in a position to be able to return to The Lodge and will therefore leave the show."
Dani said: "For medical reasons, I can't take part in any of the challenges because I am now using a sling."
"I will just be sitting around and not be able to compete and I'm not meant to move [my arm] for a week so it wouldn't be fair and there is just no point. I'll just be an extra spare part if I carry on like this."
She added: "I haven't stopped training since Christmas. I've been dieting. I did Tough Mudder last year and I didn't even hurt myself then. I've been constantly training up until now and now I've gone and dislocated my shoulder. It is what it is I suppose.
"My experience in the lead up to going into The Lodge was just amazing, I can't put it into words how amazing it was so I am absolutely gutted that I can't do any of the challenges.
"If I could go back and not dislocate my shoulder, I would definitely change it. I hope this isn't the last you've seen of me."
She will be replaced in the show and won't feature in the first public vote.
Survival Of The Fittest airs at 9PM nightly on ITV2.
