England coach Steve Borthwick has named six uncapped players in his squad for their summer internationals against Japan and New Zealand.
England face Japan in Tokyo on June 21 in their first outing since the Six Nations, then take on the All Blacks on July 6 and July 13.
Harlequins prop Fin Baxter and centre Luke Northmore, Sale pair Joe Carpenter and Tom Roebuck, Bristol's Gabriel Oghre and Northampton's Ollie Sleightholme are all included.
Having named a 36-man squad, England will train at Twickenham on Tuesday before flying out to Japan to prepare for their opening Test.
"The Summer Series presents a valuable opportunity for the continued development of this squad and is a demanding challenge to conclude the season," Borthwick said.
"The National Stadium in Tokyo is an incredible venue for Test match rugby, and we will need to be at our very best against a Japanese team who will want to play fast.
"New Zealand's home record is well documented, and we face a team who came within one point of winning a World Cup.
"The players know that they will need to be mentally strong and tactically smart if we are to get the result we want."
Full England squad: Fin Baxter, Dan Cole, Alex Coles, Chandler Cunningham-South, Ben Curry, Tom Curry, Theo Dan, Alex Dombrandt, Ben Earl, Charlie Ewels, Jamie George (c), Joe Heyes, Maro Itoje, Joe Marler, George Martin, Gabriel Oghre, Bevan Rodd, Ethan Roots, Will Stuart, Sam Underhill, Joe Carpenter, Fraser Dingwall, Immanuel Feyi-Waboso, Tommy Freeman, George Furbank, Ollie Lawrence, Alex Mitchell, Luke Northmore, Harry Randall, Tom Roebuck, Henry Slade, Ollie Sleightholme, Fin Smith, Marcus Smith, Ben Spencer, Freddie Steward.
