Scotland make changes for Springboks clash
McGeechan, who is to be replaced by former Leinster coach Matt Williams after the World Cup, also made two positional switches following the 24-15 loss to the Barbarians last month.
Kenny Logan, Andy Henderson, captain Bryan Redpath, Jason White and Andrew Mower are the newcomers, with Chris Paterson switching from stand-off to a wing berth and Gregor Townsend playing stand-off instead of centre.
