Five of the Gloucester Rugby squad joined up with England on Sunday for a summer training camp at Loughborough University.
Ben Morgan, Matt Kvesic, Jonny May, Henry Trinder and Billy Twelvetrees all met up with England team mates at Loughborough ahead of the camp with preparations beginning ahead of the Autumn Internationals and Rugby World Cup 2015.
Fifty-five players will undergo strength and conditioning assessment as well as rugby training and depart at lunchtime on Wednesday.
England Head Coach Stuart Lancaster said: "This camp will give us a chance to get the wider squad together and an opportunity to review the New Zealand tour.
"It will be an important few days for us in terms of complementing the work that the clubs have been doing in pre-season with their strength and conditioning but also from a rugby point of view. The next time we meet will be two weeks before we play New Zealand in the QBE Internationals so this time together is vital.
"In collaboration with Premiership Rugby we have been given the flexibility to announce the England Senior and Saxons squads in October, much closer to our four international matches in November. We appreciate their support of our proposal which enables time to assess the first part of the club season and therefore select players who are in form leading into an important series for us. It also allows an opportunity for players not involved in the training camp this week to put down a marker in terms of their performances ahead of the squad announcement."
A senior squad consisting of 33 players and a 32-man Saxons squad will be announced in October.

Speaking to the local media this week, Richard Hibbard expressed his excitement ahead of the West Country derby and that there is an extra spring in the step of the Cherry and Whites ahead of the tough challenge.
With such a short turnaround between the two games, and Gloucester looking to reintegrate several players into the line-up after the Autumn international series, Tom Savage told GRTV that the Cherry and Whites will keep changes to a minimum for the European Rugby Challenge Cup game in Zebre on Saturday.
Gloucester travel to Italy this weekend to take on Zebre in Round Four of the European Rugby Challenge Cup. The Cherry and Whites defeated the Italian side 35-10 last Sunday, but Director of Rugby David Humphreys is looking for an improved performance in the return fixture.
On a tough evening at Kingsholm, Gloucester could escape neither a suffocating Bath defence, nor the whistle of referee Greg Garner as six penalties and a penalty try paved the way to a 39-16 win for the visitors.
Gloucester Rugby welcome Sione Kalamafoni, Greig Laidlaw and Tom Palmer back to the starting line up and feature David Halaifonua in a matchday squad for the first time, as they resume Aviva Premiership action against Bath Rugby at Kingsholm on Saturday (kick off 5:30pm).
