London Irish's teenage full-back Henry Arundell is included in a 36-strong England training squad to prepare for July's Test series against Australia.
The 19-year-old only made his Premiership debut in February but has scored 11 tries in 15 matches for Irish and England Under-20s this season.
Arundell's club team-mate Will Joseph, the younger brother of former England centre Jonathan, is also called up.
Owen Farrell, who missed the Six Nations with an ankle injury, is back.
Leicester-bound Bath winger Anthony Watson also returns after an injury lay-off, while Saracens prop Mako Vunipola is recalled after falling out of favour and flanker Jack Willis, who suffered a serious knee injury against Italy in February 2021, is rewarded for his good form with Wasps.
Leicester's Jack van Poortvliet, 20, is another player to make the step up from England's age-grade sides as he features alongside Harry Randall and Alex Mitchell as scrum-half options for head coach Eddie Jones.
Ben Youngs, along with the experienced trio of Henry Slade, Joe Marler and Jamie George, is rested.
Sale centre Manu Tuilagi and Bath wing Joe Cokanasiga, both powerful backline runners, are included.
The training camp will run from Sunday to Tuesday as England prepare for a meeting with the Barbarians on 19 June followed by Tests against the Wallabies in Perth, Brisbane and Sydney on successive weekends, beginning on 2 July.
"We want to take a look at some younger players and prepare a base camp for the Barbarians game, particularly as we will be without the Premiership finalists, and also give some senior players a rest as we get to a crucial part of the season," said Jones.
Irish trio promoted into limelight
Adding more pace to England's attack is one of the priorities in the team's development and a series of scorching scores, included a sensational length-of-the-pitch solo effort against Toulon earlier this month, have marked out Arundell for inclusion.
He also qualifies for Scotland and Wales and will do so until he makes a Test appearance for England.
Jones said there had been a "fair bit of publicity" around Arundell and then ensured there would be more as he compared his adventurous style of play to that of Australia great Matt Giteau.
"He has exceptional pace, he probably reminds me a lot of Matt Giteau in terms of his desire to attack, not the way he plays, but his desire to attack." said Jones.
"I was particularly impressed when I went out and watched him play against Wasps [in their 42-42 draw].
"The first ball kicked to him and he knocked it on cold, that wasn't a great start when there is all this hoo-ha about him being a fantastic player.
"The next ball he gets, he spots the space in the backfield, chips and scores and that is the sort of mindset you want to see from a young player who wants to take on the game."
Joseph, also 19, is an outside centre following in the footsteps of brother and Bath star Jonathan, who made the last of his own England appearance against Wales in November 2020.
Flanker Tom Pearson is the third uncapped Irish player to make the cut. The 22-year-old is the latest talent to emerge from Cardiff Metropolitan University, after Harlequins pair Alex Dombrandt and Luke Northmore.
England achieved their first-ever series win down under on their last visit in 2016 and beat Australia at Twickenham in November.
However, a disappointing Six Nations campaign, that featured three defeats from five matches, has left Jones and his side hunting fresh momentum.
