Cammy Mather has been called out to Australia to join Scotland's World Cup squad, while Donnie Macfadyen has a shoulder injury, so Andrew Wilson and Roland Reid return to the back row.
Rory replaces Jon Steel on the right wing, Andy Hall resumes at lock in place of Joe Beardshaw and Scott Lawson takes over from Simon Gunn as hooker. Scott will be making his first start for Glasgow, though he has played as a substitute in each of the six previous Celtic matches.
