Shane Drahm has turned down an offer to remain at Franklin's Gardens to play for Worcester Warriors next season.
The Australian fly-half joined the club in the summer of 2003 after Bristol Shoguns were relegated from the topflight but has chosen to take up a new contract with the club that win promotion into the Zurich Premiership last season.
Head coach Budge Pountney said: "Drahmy has decided not to stay at Saints and we all wish him well. We did offer him a contract but Worcester came in with another offer."
Pountney added: "Although Shane has signed a contract with Worcester, I can assure our supporters he remains committed to Saints and will play with all his usual verve and enthusiasm until the end of the season."
