Saints will announce several re-signings on Wednesday - with club captain Dylan Hartley and Courtney Lawes among those committing their future to the club.
Calum Clark and Alex Waller have also penned new deals, with Ethan Waller, Gareth Denman and James Craig also staying at Franklin’s Gardens for the foreseeable future.
England hooker Hartley’s decision to remain at the club where he made his name will be a sizeable boost for Saints.
The 28-year-old was understood to have been made an offer by French club Montpellier, but has decided to reject their advances to remain in Northampton for a further three years.
Hartley has made 198 appearances for Saints since joining the club as a youngster and the Rotorua-born player is now in his fifth season as skipper.
Lawes has been an equally important presence since graduating from the Saints Academy.
The England lock has made 148 appearances for his boyhood team, becoming one of the best players in his position in world rugby.
Lawes is now a key member of the international setup and played a large part in the recent autumn international series.
Clark and Alex Waller are close to breaking into the England side, while Ethan Waller, Denman and Craig have all shown they have bright futures in the game.
