Eddie Jones has named eight uncapped players in his starting 15 for England's Old Mutual Wealth Cup clash against the Barbarians, live on Sky Sports.
There is still plenty of experience in the team with the likes of Chris Robshaw, Danny Care, George Ford, Jonny May and Mike Brown all starting with Robshaw and Ford co-captaining the non-Test side.
The eight uncapped players in the starting 15 are Jack Singleton (Worcester), Josh Beaumont (Sale), Will Collier (Harlequins), Nick Isiekwe (Saracens), Sam Underhill (Bath), Alex Lozowski (Saracens), Sam James (Sale), and Nathan Earle (Saracens).
There are seven more uncapped players on the bench including Sale's Ben Curry and Northampton-bound prop Jamal Ford-Robinson.
Head coach Eddie Jones said: "I'm excited about this squad playing the Barbarians on Sunday. The players have trained really well with intensity over the last few weeks and now we need to put that onto the field this weekend."
"While we have some really experienced players starting the game there is a great opportunity for some of the younger players to show what they are about against a Barbarians team full of quality international players.
"We will be treating this game as a Test match and expecting the Barbarians to start the game quickly. This match will be crucial preparation ahead of our two-Test series against Argentina next month.
"I've decided to have co-captains this weekend with Chris Robshaw and George Ford. We need the responsibility of leadership shared.
"Chris will look after the forwards and defence while George will look after the backs and attack. It splits the responsibility nicely and with so many younger players there, we need co-captains rather than just one guy responsible for everything."
