Scotland fly-half Ruaridh Jackson has signed a two-year contract extension with the Glasgow Warriors.
The 23-year-old, who has 11 caps and started three of Scotland's four Rugby World Cup games, is now committed to the Warriors until May 2014.
Jackson told www.glasgowwarriors.org: "I'm absolutely convinced this is the right place for me to be over the next few years. Like every player, I'm ambitious about what I want to achieve in the game and I'm excited that Glasgow Warriors and Scottish Rugby are committed to moving the club forward on and off the pitch."
He added: "We've got a great group of hungry, talented players here and there's a real chance for us to push on as a group and achieve success for Glasgow Warriors."
Aberdeen-raised Jackson signed his first professional contract with Glasgow in May 2008.
Warriors head coach Sean Lineen said: "It's no secret that I've been a huge fan of Ruaridh since I first clapped eyes on him playing for Robert Gordon's College five years ago, and he's come on massively in the time he's been involved with Glasgow Warriors.
"He's already shown himself capable of holding his own as a Test fly-half and if he continues to show the same outstanding level of application he'll go from strength to strength."
Jackson could make his first Glasgow appearance in Friday's match with the Ospreys, if he can prove his fitness following a hamstring injury sustained against England in Auckland on October 1.
