Glasgow have announced the re-signing of back-row duo Rob Harley and Tyrone Holmes, who will stay at Scotstoun until at least May 2016.
Harley joined Glasgow in 2010 and has made 93 appearances for the RaboDirect PRO12 side, with the 23-year-old now a regular in their line-up.
"I've really developed as a player over the last four years, getting regular game time at the Warriors and playing for Scotland," he told the club website.
"I feel like this is the perfect place for me to continue my development, working with a great group of players and coaches."
Meanwhile, Holmes joined the club during the off-season on a one-year deal and has featured regularly this season, playing seventeen times.
"It was a great decision to come to Glasgow in the summer and I'm delighted to be staying for another two years," he said.
"My father was born in Peebles and he is so proud of what I've achieved in Scotland this season. I've already sent my Scotland A shirt back to him in South Africa."
