also available for Glasgow are all eight of their players who were in Scotland's match squad for the Calcutta Cup international against England at Twickenham last Saturday - Sean Lamont, Andy Craig, Gordon Bulloch, Rory Lamont, Dan Parks, Graeme Beveridge, Andrew Henderson, and Jon Petrie.
Friday's match is vital for Glasgow as they seek to strengthen their bid for a Heineken Cup top seeding next season and a place in the Celtic Cup next month. Glasgow have already qualified for the Heineken, but they have to overtake Edinburgh to become Scotland's top seeds.
