Sale have confirmed that fly-half Charlie Hodgson will leave the club at the end of the current season.
The 30-year-old former England star has been at Sale for 11 years, but has told the club this will be his last campaign in a Sharks shirt.
"Irrespective of what has happened this season at the club I wanted a new challenge elsewhere," Hodgson said in a statement released by Sale.
"I am not getting any younger and wouldn't want to hang up my boots wondering whether I should have moved."
The Halifax-born Hodgson has scored a Premiership record 1,753 points for Sale after joining them from university.
Sale chief executive Mick Hogan said: "We are naturally disappointed that Charlie has told us that he will be leaving the club but would like to thank him for all his efforts over the past 11 seasons.
"Without doubt he will be considered one of the greatest players to ever play for Sale Sharks.
"We made it clear to Charlie that we wanted him to stay at Sale but understand his reasons for wishing to move on.
"We know what a difficult decision this has been for Charlie to make and the club are thankful for the early indication he has given us on his future."
Hodgson has been linked with Sale's Premiership rivals Saracens, although a move across the Channel to France may also appeal.
