Scotland international Henry Pyrgos has signed a new two-year contract with Glasgow Warriors.
The 27-year-old scrum-half has amassed over 100 appearances for the Pro12 side and won 18 caps for his country since arriving at Scotstoun in 2010.
Pyrgos, named co-captain of the Warriors at the start of this season, has now agreed to extend his stay at the club until at least May 2019.
"I'm really happy to sign for another two years, it was an easy decision. I love everything about Glasgow Warriors and the club means a huge amount to me," said the playmaker.
"I've had a brief chat with Dave Rennie [Glasgow's next head coach] and he told me about his vision for the club and his rugby philosophy and it's exciting. What he's done in the game speaks for itself and to have someone of Dave's quality coming in is brilliant for the club.
"This is my seventh year at the Warriors and winning the Guinness PRO12 two years ago has been the standout moment.
"I'm excited for the future here and we'll be working extremely hard to continue to compete for trophies every season. I believe we have a squad capable of doing that and that's the main reason I wanted to stay."
