The Glasgow contingent is once more led by Joe Roberts, who relinquishes the captaincy but continues at hooker after impressing in last weekend's 36-10 win away to Italy in Treviso.
Rory Purvis packs down at number eight again after featuring in the pack last Friday night, the Kilmarnock-born back-rower looking to continue his fine run of form.
A brace of Glasgow academy prospects complete the cohort on the bench, as Ollie McKenna and Jackson Rennie provide the cover at prop as they await their opportunity from the bench.
