Four Exeter Chiefs players are training with England this week.
Tom Johnson, Jack Nowell, Henry Slade and Luke Cowan-Dickie met up with the squad on Sunday and are taking part in strength and conditioning assessment as well as rugby training until Wednesday.
That is despite the fact five-times capped Nowell and uncapped hooker Cowan-Dickie are currently injured.
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."
A 33-man senior squad for the autumn internationals, as well as a 32-man Saxons squad, will be announced in October.
