Robshaw rested for England tour
Regular captain Chris Robshaw has been left out of England's 32-man squad for an encounter with the Barbarians and a three-match tour of Uruguay and Argentina.
Other England regulars omitted were the Harlequin flank's teammate Danny Care, Toby Flood (Leicester Tigers) and Brad Barritt and Chris Ashton (both Saracens).
Robshaw is being rested, despite having made it clear he was keen to tour after missing out on selection for the British and Irish Lions.
Captained by Northampton's Tom Wood, the England squad includes five players who are 21 or under, the youngest of whom is Wasps No.8 Billy Vunipola, who represented England Under-20 last year.
The squad includes 11 uncapped players.
England coach Stuart Lancaster said: "We're really looking forward to this tour and we've selected a young and exciting side which I'm sure will do the country proud in a tough series of matches.
"The key principles in selection were threefold: first and foremost to win the games but also to develop strength in depth and more options in certain positions, and to give one or two players a physical and mental break.
"We feel we've got the balance right and have given places to a number of players who have shone in the Premiership this season, one or two who have been on the fringes for a while, and several players who have been involved over the last year or so.
"This is everyone's chance to step up.
"Tom Wood will captain the side and I am sure he will do a fantastic job as he has the respect of all the players and management and we are looking forward to other leaders developing in the absence of some senior players.
"A few are being rested after a hard campaign but they will, of course, be considered by the British & Irish Lions should they be required."
The uncapped players are forwards Rob Buchanan (Harlequins), Calum Clark (Northampton Saints), Matt Kvesic (Worcester Warriors), Ed Slater (Leicester Tigers), Henry Thomas (Sale Sharks) and Billy Vunipola (London Wasps), and backs Kyle Eastmond (Bath Rugby), Jonny May (Gloucester Rugby), Joel Tomkins (Saracens), Christian Wade (London Wasps) and Marland Yarde (London Irish).
England – minus the players from the Premiership Final the previous day – are taking on the Barbarians at Twickenham Stadium on May 26.
They then play a CONSUR XV, representing the South American nations, in Montevideo, Uruguay, on June 2, and then Tests against Argentina in Salta (June 8) and Buenos Aires (June 15).
Anthony Allen (Leicester Tigers) and James Haskell (London Wasps) were not considered on medical grounds.
