Ryan Mills, Will Spencer and Perry Humphreys are among 20 players who will assemble at the Lensbury Hotel in Teddington on Tuesday 9 May until Thursday 11 May for an England training camp focusing on strength and conditioning.
The Warriors trio have impressed during the 2016/17 campaign and will all be hoping for a call-up for their country this summer as they all look to earn their first caps.
Mills has enjoyed a fine season playing predominantly at fly-half in the absence of some key players, slotting 121 points in 17 games including a 24-point haul as Warriors defeated Saracens in February.
Lock Spencer has had quite the journey in the last few months. Having not played a game in almost two years, he made his long-awaited Warriors debut in December and has since gone on to make 17 appearances, becoming a mainstay of the side.
He scored vital tries in clashes against Bristol Rugby and former club Bath Rugby as Warriors picked up important wins to beat the drop.
Humphreys, 22, has just completed his third season at the Club and is another success story having made his Premiership debut in September, scoring three tries in his first four top-flight games.
He has gone on to make 18 appearances in the 2016/17 season, causing havoc against some of the best wingers in the country including Anthony Watson, Charlie Sharples and Denny Solomona.
