Rory Lamont has become the latest player to commit his future to Glasgow.
Lamont has signed full-time after impressing on a short-term deal although his older brother, Sean, has opted to join Northampton Saints.
Glasgow have now secured 11 players on new or renewed contracts, including Craig Hamilton from Newcastle Falcons.
The Scotland international lock forward will join Glasgow in June for the start of preparations for next season.
Glasgow head coach Hugh Campbell said: Were delighted to have signed experienced players together with some young Scots who have been coming through the system.''
