Five Saints players have been named in England’s 44-man pre-season training squad that gets together on Saturday at Lensbury Hotel in Teddington.
The players named in head coach Eddie Jones’s squad are Piers Francis, Courtney Lawes, James Haskell, Paul Hill and captain Dylan Hartley.
Former Saints winger Chris Ashton is also included in an England squad for the first time in two years.
The training camo runs from Saturday to Monday, and coach Jones said: “With just over 12 months until the Rugby World Cup, it is an important time.
“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.
“We have 44 players coming in plus another 15 who are strongly in contention for the Quilter Internationals in November.”
England’s next training camp will be from September 23-25 in Bristol, before joining up on 24 October to prepare for the autumn internationals in November.
England will play four matches in the autumn against South Africa (November 3), New Zealand (November 10), Japan (November 17) and Australia (November 24).
