Scotland internationals Jon Petrie and Donnie Macfadyen have signed new contracts with Glasgow Warriors.
The back row forwards are an integral part of head coach Hugh Campbell's team with number eight Petrie also captaining the side this season.
Petrie, 28, has signed a two-year deal, while 25-year-old flanker Macfadyen has committed himself to a further three years at the club.
Campbell said: ''It's fantastic news for Glasgow Rugby that Jon will be with the squad for the next two years.
''He's been outstanding this season, and he brings great experience to the squad not only as a player but also as captain.''
He added: ''It's a real boost for Glasgow Rugby to have Donnie with us for at least three more years.
''He's rated as Scotland's top number seven, but he has been unfortunate with injury this season.''
