Ben Te’o and Jack Singleton have been named in England’s 44-man pre-season training squad to convene at the Lensbury Hotel from Saturday 4 August until Monday 6 August.
Chris Ashton (Sale Sharks) is selected having returned to England this summer from playing in France with Toulon.
The 31-year-old winger, who scored 19 tries in 39 Tests for England, last played international rugby in 2014.
England coaches will have a chance to look at a number of new or young players including Gabriel Ibitoye (Harlequins), Joel Kpoku (Saracens), Jordan Olowofela (Leicester Tigers) and Michael Rhodes (Saracens).
A number of players rested for the tour to South Africa were not considered for this camp but will be watched closely in the club season.
England Head Coach Eddie Jones said: “This is a pre-season camp so a lot of our players, particularly the ones who went on the South African tour, have just started training with their clubs so it’s just a chance to get a group of players together to have a chat about the season ahead and look at the important areas in developing the team. With just over 12 months until the Rugby World Cup, it is an important time.
“We haven’t selected everyone. There are a number of players we rested from the tour that we have allowed to continue their pre-season with their clubs.
“This camp is all about individual preparation – it’s about looking to see how we can help each of the players improve, how we can help with their selection for the national team because we have 44 players coming in plus another 15 who are strongly in contention for the Quilter Internationals in November.
“We have one day of training at this camp, a September camp, then a week before the South Africa game so every minute counts. We want to make sure we use every minute as productively as we can so that is the target of the camp.”
England’s next training camp will be Sunday 23 September until Tuesday 25 September in Bristol before joining up on Wednesday 24 October to prepare for the Quilter Internationals in November.
England will play four matches in the upcoming Quilter Internationals against South Africa (3 November), New Zealand (10 November), Japan (17 November) and Australia (24 November). Kick-off for all games will be 3pm live on Sky Sports HD.
