Scotland lock Jonny Gray has signed a new three-year contract with Glasgow.
The 21-year-old has followed World Cup team-mate Finn Russell in extending his stay with the Warriors until May 2018.
Gray has made 40 appearances for Glasgow after following his brother, Richie, into the team in December 2012, and has won 19 Scotland caps, four of them during the World Cup.
He said: “I’m very happy to be staying at Glasgow. It’s my home club and I’m just glad I’ve had the opportunity to sign.
“It’s been a fantastic few years’ development for me. When I was younger I always had the ambition to play for Glasgow and Scotland, and playing in a Rugby World Cup has been a fantastic experience.
“It’s great to see Finn signing as well and there is a lot of talent at the club and it’s great to be a part of it.
“Everyone works very hard and that just makes you want to improve as a player and improve the team as well. To have the opportunity to work with the coaches and players at the Warriors is fantastic.
“Scotstoun is a fun place to be, and everyone works hard for each other and the culture is great.
“I used to go and watch my brother playing at Firhill and it’s incredible to see the crowds growing since we moved to Scotstoun. The fans are really passionate and they make it a very special place to play.”
