Newcastle Falcons' Mark Wilson has been named in England's 31-man squad for next week's training camp in London.
Head coach Eddie Jones said: “Next week we will add some players and be looking to improve our physical conditioning, ability to understand how we want to play the game and start to increase the pressure at training.
"We have a couple of players going back to their clubs as we feel it is in their best interests in terms of the World Cup to do that, and we will consider their participation in the squad further down the track.”
England’s official Rugby World Cup training squad will be announced by Jones at Japan House on Thursday 4 July.
England will play Wales (11 August) and Ireland (24 August) at Twickenham Stadium and Italy (6 September) in Newcastle as part of the Quilter Internationals as well as an away fixture against Wales (17 August) in Cardiff.
England will travel to Treviso, Italy for a heat camp from 22 July until 2 August before returning to Italy on 28 August until 5 September. The squad will also be based in Bristol for a week in July (14-18) and in August (12-16) ahead of England’s away match against Wales.
