Jake Quickenden, Ulrika Jonsson and Vicky Pattison have reportedly dropped out of the new series of Celebrity SAS: Who Dares Wins just a few days after filming started.
The new run of the notoriously-difficult reality show is currently being filmed in Scotland, with Ant Middleton putting a fresh batch of famous faces through their paces in a test of physical and mental endurance.
According to The Sun, Jonsson and Pattison found the experience too challenging and decided to quit, while Quickenden has had to be flown to London after suffering an injury.
"Ulrika was so keen but not long after it started she had a meltdown and quit," a source told the newspaper. "She's had a back issue and it was evident she wasn't cut out for the tasks.
"Vicky also handed in the towel not long in.
"On the same day she left, it turned into chaos as Jake pulled up in agony. It's believed he could have torn a bicep.
"Everyone hopes he'll return but it depends if he'll recover in time. It's not great losing people but it proves how hard it is."
