Among nine players to be added to the squad following the Gallagher Premiership semi-finals, Furbank and Sleightholme linked up with the squad alongside fellow Saints Paul Hill, Lewis Ludlam and Alex Mitchell as it reconvened today at The Lensbury ahead of their opening game in a week’s time – England A v Scotland A at Mattioli Woods Welford Road (Sunday 27 June, kick-off: 2pm).
Jones will name a further updated squad on Monday 28 June, following the Gallagher Premiership Final and England A v Scotland A.
England will then play two Test matches at Twickenham Stadium – against USA on Sunday 4 July (kick-off: 2pm) and Canada on Saturday 10 July (kick-off: 3pm).
Jones said: “We had a really good training week last week. We’ve now added some new players and are looking forward to working with them.
“The players who aren’t with us now acquitted themselves really well in training and though they are disappointed to go home, we’ve made the point to them that if they keep working hard then there will be more opportunities for them.
“We will treat the week as a Test week, everyone will work hard and be ready for a competitive game on Sunday."
