Steffon Armitage and Nick Abendanon have been left out of England's preliminary squad for the Rugby World Cup as expected.
England head coach Stuart Lancaster has named 50 players for training camps in Surrey and Colorado before submitting a final group of 31 ahead of this year's tournament.
Saracens wingers Chris Ashton and David Strettle are both included while there are plenty of young uncapped talents in Luke Cowan-Dickie, Maro Itoje, Henry Slade and Elliot Daly.
England will face France home and away and Ireland at Twickenham as part of the warm-up matches as they build towards RWC 2015.
“We are excited to name this extended squad which allows us to look at a wide group of players who have been pushing hard for selection in training with us or playing well for their clubs this season," said Lancaster.
“It’s great to be able to include Alex Corbisiero, Joe Launchbury, Ben Morgan, Ed Slater and David Wilson, who missed the Six Nations because of injury and are close to returning to play or have recently begun playing again.
“There are a lot of experienced internationals within the squad with the likes of Chris Ashton and David Strettle, who are in great form, returning and it’s also good to have young players like Luke Cowan-Dickie, Elliot Daly, Maro Itoje and Henry Slade in there who have come through our player development pathway and had great seasons for their clubs.
“Ben Foden, Joe Simpson and Tom Croft have not been included at this stage due to ongoing rehabilitation from injury but will hopefully come into consideration nearer the tournament.
“A number of this 50-man squad, such as Joe Launchbury, Elliot Daly, Danny Cipriani and Marland Yarde will be involved in the England XV side playing the Barbarians on May 31 following the Premiership semi-finals.
"There will also be opportunities for the likes of Dave Ewers and Christian Wade who just missed out on the initial selection but could come back in further down the line.”
The England squad to play the Barbarians will be announced at 5pm on Sunday once the Premiership finalists are known as a number of players from the losing semi-finalists could be involved.
Players from Gloucester would also not be considered should they reach the Champions Cup qualification final.
This training squad is set to be reduced prior to the training camp in Denver and subsequently reduced again as the warm-up internationals approach with the final 31 players for the Rugby World Cup being announced by the August 31 deadline.
