Celebrity SAS Who Dares Wins has reportedly been thrown into complete chaos after six stars were forced to quit after suffering horrific injuries.
Three of the stars are said to have been placed in hospital in one day.
It's the highest number of medical discharges the Channel 4 show has ever seen since it's formation in 2015.
The gruelling punishing regime has reportedly seensix stars crumble in the special new series of Celebrity SAS: Who Dares Wins which is set in Thailand.
The Wanted singer Siva Kaneswaran, ex footballer Jermaine Pennant and Paralympic cyclist Jon-Allan Butterworth all passed out during the intensive marching test, according to The Sun.
The trio crumbled under the pressure while they were forced to walk in the blazing heat while carrying heavy bags on their back.
Siva, Jermaine, and Jon-Allan were forced to quit the intensive regime after doctors insisted that they could no carry on amid their horror injuries.
Former Love Island beauty Montana Brown was also reportedly left in excruciating pain after she dislocated her kneecap and rugby star Gareth Thomas faced pain when he pulled a hamstring muscle leaving him in agony.
Both Montana and Gareth are said to have have now been discharged from the show.
And former TOWIE star James Argent was also medically discharged from the show, making him the sixth contestant to quit for medical reasons.
The reality TV star was discharged by doctors after he contracted trench foot and jungle rot while filming in Thailand.
Lifting the lid on the shock injuries, an insider told The Sun: “They are celebrities, not soldiers. They aren’t used to the hot, harsh conditions and being pushed to their limits.
“The people who fell ill and were injured were not unfit or out of shape. Siva, Jermaine and Jon-Allan are all fit blokes but all individually blacked out and had heat stroke.
“James’s issues with his feet were awful too. He was in agony as the infection took hold because of the wet boots and he could suffer for months now.”
The Thailand series of Celebrity SAS is due to wrap filming in the next couple of weeks.
The hotly-anticipated series will air on Channel 4 next year.
The Mirror has reached out to a spokesperson for comment on this story.
