Scotland back-rowers Rob Harley, Chris Fusaro and Ryan Wilson have agreed new two-year deals with Glasgow.
The trio will be staying with the reigning Guinness PRO12 champions until at least May 2018 and follow Jonny Gray, Finn Russell, Pat MacArthur, Fraser Brown, Alex Allan, Sila Puafisi and Ali Price in committing their futures to the club.
Wilson's Warriors future looked in doubt when he was found guilty of assault last year. But the 26-year-old -- who joined Glasgow from English Championship side Moseley and has so far made 104 appearances -- is delighted he will be staying put.
"This is my sixth season at the Warriors and I've loved my time here," he said.
"Being involved at the Rugby World Cup with Scotland was incredible and I want to continue to play at the highest level. By staying at Glasgow, I'll have the opportunity to do that."
Flanker Harley has become one of Glasgow's most consistent performers having racked up 131 appearances for the club he joined in 2010. He has captained the Warriors on a number of occasions and has played 17 times for Scotland.
The 25-year-old said: "We've been very successful in my time here and there is a great culture at the club. There is a really good work ethic and a desire from all the players to learn more and improve every day.
"I supported Glasgow growing up and was a season ticket holder at Firhill. To come out of the stands and onto the pitch was an amazing experience and what you dream of when you're growing up.
"It was great to get a taste of the success we had last year, so my aim in the next two years is to keep winning trophies and push on in Europe.
"I'd like to use the excellent coaches we have here to improve my game and become a better player."
Fusaro has also made over 100 appearances for Warriors since joining the club in 2010.
The openside flanker, capped four times by Scotland, added: "Glasgow has been my only club since I started professional rugby and we've come on a long journey, but I still think we've got a lot further to go.
"I signed the same year as Ryan and Rob and we've formed a tight-knit group in the back row. It's great the club has managed to hold on to so many guys who have been here from the start."
