Current England internationals Teimana Harrison and Paul Hill have signed new contracts with Aviva Premiership club Northampton.
The Saints have announced new deals for six players, with the list completed by former England flanker Tom Wood, his back-row colleagues Jamie Gibson and Ben Nutley, plus prop Adam Parkins.
Wood, who will skipper Northampton next season, joined the club six years ago and was a member of England's 2015 World Cup squad.
Unlike Harrison and Hill, though, he has not featured for his country since Australian Eddie Jones became head coach.
Harrison, 23, and 21-year-old Hill both made their Test debuts this year and were members of the England squad that toured Australia last month, claiming a 3-0 Test series triumph against the Wallabies.
Gibson, meanwhile, joined Saints from their Premiership rivals Leicester a year ago, and Northampton academy product Nutley has made more than 60 first-team appearances at Franklin's Gardens, with Parkins among a group of promising front-row prospects in Saints' ranks.
"We are delighted that all six players have signed new contracts to stay at Franklin's Gardens," Northampton rugby director Jim Mallinder said.
"We've seen them all develop massively in their time at the club, and to have these deals agreed well before the start of the 2016-17 season means that we can plan with certainty for the future."
Northampton have also delivered upbeat fitness bulletins on a number of players, including Wood, who suffered injuries towards the end of last season or during recent summer tours.
Saints say that Wood (neck), England forward Courtney Lawes (ankle), Ethan Waller (toe) and Tom Stephenson (foot) should all be fit for the start of the new Premiership season after undergoing surgery.
And wing George North is also on course to make the Premiership opener against Bath in early September. He suffered a hamstring injury during Wales' New Zealand tour last month.
But wing Jamie Elliott will miss the season's opening few weeks following shoulder surgery, and centre Rory Hutchinson is continuing his recovery after suffering a serious ankle injury during Scotland's Under-20 World Championship campaign in June.
