Flanker Chris Fusaro has signed a new two-year deal with Glasgow.
The 24-year-old made his Scotland debut in the Calcutta Cup defeat by England last weekend after coming through the ranks with the Warriors, who he joined in 2010.
His new contract will keep him at the club until the summer of 2016.
"Since joining the Warriors I've never looked back and I'm delighted to be staying at the club for another two years," Fusaro said.
"I'm enjoying working with the coaches and my game has really developed over the past few years.
"I was so proud to make my Scotland debut on Saturday and although I was very disappointed with the result, I will never forget the experience.
"I believe the best place for me to be is in Glasgow, as it's a club with a very bright future with success on the horizon."
Coach Gregor Townsend added: "It's fantastic news for the club that Chris has decided to stay and continue his development in Glasgow.
"Chris has had a very good season, which has led to him winning his first cap on Saturday. He displays leadership qualities every day at the club.
"He epitomises what you want to see in a rugby player and is very well respected by everyone in the group."
