England coach Eddie Jones has named 17 uncapped players in his 32-man squad for next month's two-test tour of Argentina.
Bath flanker Sam Underhill keeps his place despite picking up an injury during his debut in England's 28-14 win over the Barbarians at Twickenham on Sunday.
Denny Solomona is also in the squad despite suffering a foot sprain during England's recent training camp in Brighton, although Marland Yarde of the Harlequins has been called up as cover.
"I'm really excited about this test series in Argentina. It is a big opportunity for this group and we are going out there to win 2-0," Jones said in a statement on Monday.
"We are looking forward to a good week of preparation in London before we depart this weekend."
Captain Dylan Hartley, second-rower Joe Launchbury and flanker Chris Robshaw are the most experienced forwards in the squad, with a combined 181 caps between them.
Harlequins' fullback Mike Brown and scrum-half Danny Care are the most experienced backs in the squad, alongside George Ford and Gloucester's Jonny May.
The two-match series kicks off on June 10, with the second game a week later.
