Head coach Eddie Jones has named a 36-player training squad ahead of England's tour of Australia, the standout selection being that of teenager Henry Arundell.
Having only won two of their five matches during the Six Nations, England and Jones will be under pressure to deliver Down Under in July.
The touring squad will not be announced for a number of weeks, but Jones has taken the opportunity to assess the progression of full-back Arundell.
Since making his Premiership debut in February, the 19-year-old has contributed 11 tries in just 15 outings, some of those games taking place at Under-20 level with England.
Twenty-year-old scrum-half Jack van Poortvliet, who represents Leicester Tigers, also earns a call-up, while Jack Willis returns after a serious knee injury last year.
Speaking on the squad, Jones is quoted by BBC Sport as saying: "We'll focus on how we want to play, how we want to be as a team off the field and continue to develop the squad cohesiveness and behaviours. It is also 16 months to the World Cup and every minute counts. We want a hard-working and enjoyable environment for the players and to make sure we are all on the same page.
"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."
The first of three Test matches against Australia is scheduled for July 2.
