Glasgow have announced that lock Al Kellock has signed a new deal that keeps him at the Warriors until 2015.
The 31-year-old has committed to the Warriors in a contract that includes options to remain on the playing staff as well as work in an ambassadorial role with the club and the Scottish Rugby Union.
Kellock moved to the Warriors from Edinburgh in 2006 and was immediately made captain, a role he has retained in the seven seasons since.
"It's a privilege to play for Glasgow Warriors and I'm honoured to be captain of this club," the former Scotland skipper told the club website.
"Over the next three or four years I have one goal and that's to help this club win silverware. There is a strong squad and work ethic here and I want to be at the forefront of the push for success.
"I'm still keen to develop as a player and learn from the coaches at Glasgow. I'm still working hard at my game, still trying to improve and I have more to give to the Warriors.
"We have been shaping up over the last two or three seasons to do something special for the game in Scotland and compete with the best teams in Europe.
"Winning a trophy against these sides is something I desperately want to happen for the game of rugby in Glasgow."
