England coach Eddie Jones has called up another five uncapped players as part of a training camp squad in preparation for next weekend's non-cap match against the Barbarians and July's tour of Australia.
Prop Kyle Sinckler, however, will miss the trip to Australia after being ruled out with a back injury. The Bristol Bear's forward has not played since April, and it is understood he will take the summer off to ensure full fitness for next season.
Jones' announcement on Monday takes the total number of uncapped players in the 35-man squad to 16, with many experienced players unavailable due to being involved in the Premiership semifinals.
There are first involvements in a senior England camp for Biyi Alo, Charlie Atkinson, Freddie Clarke, Sam Jeffries and Patrick Schickerling.
Winger Jonny May returns after recovering from a knee injury while injured duo Luke Cowan-Dickie and Anthony Watson will also be in camp undertaking rehabilitation work.
Jones, without a raft of players as Saracens take on Harlequins and Leicester Tigers play Northampton Saints on Saturday, said: "It's a great opportunity to learn about some new players and see what potential they have to play a part in the Australia tour.
"We look forward to continuing the good work from our last camp in developing this team on and off the pitch."
England face Australia in Perth (July 2), Brisbane (July 9), and Sydney (July 16).
