Adam Ashe has signed a new two-year deal with Glasgow Warriors that will keep him at the club until May 2017.
The 21-year-old has played eight times for Warriors and has already featured three times for Scotland.
"This is a great club with a really bright future, so I'm happy to be staying in Glasgow for another two years," said Ashe.
And Glasgow head coach Gregor Townsend added: "He is a hard-working back-rower with an excellent set of skills."
Ashe is the eighth player to commit his future to the Warriors this season, following new deals for Stuart Hogg, Peter Horne, Lee Jones, Leone Nakarawa, Henry Pyrgos, Tommy Seymour and Josh Strauss.
Number eight Ashe signed his first professional contract with the Warriors in August 2014, after coming through the Scottish Rugby Elite Development Programme.
The 21-year-old has three caps for his country, after making his debut against South Africa in June. He also featured against Argentina and New Zealand in the autumn Tests last November.
"I've been at the Warriors since I was 19 and it has really helped me progress as a player," Ashe added.
"I'm now getting the opportunity to play regularly for Glasgow and I've played a few games for Scotland, so it's been a great 12 months for me and hopefully there's more to come."
Townsend described Ashe's new deal as "great news for the club".
"Although he's predominately a number eight, he can play across the back row and he would have undoubtedly played a lot more this season if it hadn't been for injury," added the Warriors head coach.
"He's now getting close to returning to action, which will be a big boost for us at a very important period of the season."
