The former 'Geordie Shore' star reportedly left the programme - which sees celebrities face their toughest challenges, as they each endure gruelling tasks recreated from the SAS’s secret selection process - on the same day as former 'Hollyoaks' star Jake Quickenden got injured, leaving the programme in "chaos" after the triple departure.

An insider said: "'SAS' is notoriously the hardest show on telly and it pushes the celebs to their limits.

"On the same day she [Vicky] left, it turned into chaos as Jake pulled up in agony. It’s believed he could have torn a bicep."

Former 'I'm A Celebrity... Get Me Out Of Here!' star Jake was flown from Scotland - where 'SAS' is being filmed - to London to see a specialist surgeon.

Despite his injury, it is hoped he will return to the series.

The insider added to The Sun newspaper: "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."

TV presenter Ulrika, 53 - who is thought to have had a "back issue" - and 32-year-old Vicky are both said to have found the tough tasks too much.

Earlier this month, it was reported Ulrika had joined the cast of the show after her four kids - Cameron, 26, Martha, 16, Bo, 20, and 12-year-old Malcolm - inspired her to sign up for the programme.
