While former Love Island star Montana was left in tears after dislocating his kneecap, rugby player Gareth Thomas was left in agony after pulling a hamstring and former TOWIE star James was given trench foot and jungle advice.
According to The Sun, Siva, Jermaine and Jon-Allan collapsed while walking in the tropical heat while carrying heavy bags during a march test and a doctor ruled they could not continue on the series.
TV personality Montana Brown, sportsman Gareth and reality star James all suffered their ailments at different times and doctors also wrote them off the show.

A source told the publication: ‘They are celebrities, not soldiers. They are not used to the hot, harsh conditions and being pushed to their limits.
‘The people who got sick and were injured were not unfit or out of shape.
‘Siva, Jermaine and Jon-Allan are all healthy guys but all individually black and had heat stroke.
‘James’ problems with his feet were also terrible. He was in agony as the infection took hold due to the wet boots and he was suffering for months now.
Filming for the Thailand series is due to wrap up soon with the show airing next year.
The season’s line-up was confirmed at the start of the month, with 16 celebrities signing up to take part.
As confirmed by MailOnline, James agreed to take part after losing 14 stone following his life-saving stomach surgery.
Before his accident during filming, a source exclusively revealed that James was ‘determined’ to make it to the end of the course and wanted to prove he was capable of tackling the most grueling TV show after previously speaking about his struggle with drug addiction, depression and overeating.

A show insider told MailOnline: ‘James has been through so much in his life but now after months of recovery and working on himself – he is ready for a challenge of this magnitude.
‘It’s not just the physical aspect of the show for James, he’ll be tested mentally and given the chance to talk about everything he’s experienced in recent years.
‘Producers of SAS are always looking for celebrities who have a story to tell and are prepared to take on the challenge – James is the perfect signing.’
