The Bear Grylls reality series will be back in 2016 for a second run on ITV after a successful debut earlier this year.
31-year-old soap star Ryan - who is set to quit Corrie after 15 years - has apparently been dropped from the new Mission Survive line up over "concerns about his lifestyle", The Sun newspaper reports.
A source told the tabloid this weekend: “Ryan saw Mission Survive as great exposure. Producers wanted him as he’s a character and popular with the ladies. But then everything started to unravel.”
The first ever series of Mission Survive aired on ITV earlier this year and saw eight celebs take on a ridiculous trek across South America, with Bear as their guide.
They had to deal with everything mother nature could throw at them as they navigated their way through the jungle.
The stars, which included The Wanted singer Max George and rugby hunk Mike Tindall, had to learn how to make fire and build shelter, as well as take on challenges including abseiling and crossing raging crocodile infested rivers.
ITV has announced a second series will air in 2016 with Princesses Beatrice and Eugenie tipped for the line up.
