Fly-half Stephen Myler is among four players to agree new contracts with Premiership champions Northampton.
Versatile back James Wilson, 31, plus centres George Pisi, 28, and 20-year-old Tom Stephenson have also extended their stays with the Saints.
Myler, 30, has 1,152 points in 141 Premiership appearances for the club.
"We're delighted that all four have decided to stay with us and continue their career at the Saints," said director of rugby Jim Mallinder.
"They are all quality players who have shown time and again that they have the ability and composure to compete at the highest level of the sport, and they will remain important members of the squad for years to come."
The lengths of their new contracts have not been disclosed by the club.
Saints have also announced the departure of centre Glenn Dickson, 28, with immediate effect after 14 appearances for the club.
England internationals Dylan Hartley and Courtney Lawes were among seven Northampton players to sign new deals earlier in December.
Mallinder's side are two points clear of Bath at the top of the Premiership after Saturday's narrow home win over Leicester, having played most of the match with 14 men following hooker Hartley's first-half red card.
