Denny Solomona and Sam Underhill are among 15 uncapped players named in England's 31-man rugby squad for their June tour to Argentina.
Rugby league convert Solomona, who qualifies for the RBS 6 Nations champions on residency grounds, and back row prospect Underhill feature in a 31-man party that is missing Danny Cipriani.
Coach Eddie Jones has opted against resting those senior players who have been overlooked by the British and Irish Lions, retaining Dylan Hartley as captain and selecting the likes of Chris Robshaw, James Haskell and Mike Brown.
Forwards: Will Collier, Luke Cowan-Dickie, Ben Curry, Tom Curr, Charlie Ewels, Ellis Genge, Dylan Hartley (captain), James Haskell, Paul Hill, Nathan Hughes, Nick Isiekwe, Joe Launchbury, Matt Mullan, Chris Robshaw, Sam Underhill, Harry Williams, Tom Wood.
Backs: Mike Brown (vice-captain), Danny Care (vice captain), Joe Cokanasiga, Nathan Earle, George Ford (vice captain), Piers Francis, Sam James, Alex Lozowski, Harry Mallinder, Joe Marchant, Jack Maunder, Jonny May, Henry Slade, Denny Solomona.
