Greig Laidlaw will call time on his Gloucester career and move to Top 14 side Clermont Auvergne at the end of the season.
The Scotland scrum-half has spent two years with the Premiership outfit after joining from Edinburgh, who he helped to defeat in the 2015 European Challenge Cup final.
With his deal at Kingsholm expiring when the 2016-17 campaign concludes, Laidlaw is looking ahead to a fresh challenge in France.
"At this stage of my career, the offer to test myself and develop my game even further in a different environment was just too good to turn down," he said, with the move having been announced on his 31st birthday.
"I've thoroughly enjoyed my time at Gloucester. It's a fantastic club which enjoys tremendous support. The squad contains a great group of boys, I love playing at Kingsholm and it's been a genuine honour to captain the side.
"Since I first moved south, I feel that my game has developed tremendously for playing in the Gloucester team in the Aviva Premiership and it's a period of my career that I'll always look back on fondly."
