Matt Phillips and Phil Bardsley will not travel with Scotland for the friendly against Slovenia after being ruled unfit.
Blackpool winger Phillips has a hamstring injury while Sunderland full-back Bardsley has a suspected tear in his calf.
The pair join Celtic midfielder Scott Brown in pulling out of the squad. Wigan midfielder James McArthur was added after Brown withdrew on Sunday night, but no-one else has been called up.
