Centre-back David Bates could win his first cap in seven years after being added to the Scotland squad for the matches against North Macedonia and Switzerland.
Bates, playing with Amedspor in Turkey, won the last of his four Scotland caps in 2019 and replaces fellow defender Luis Binks, who has withdrawn.
As well as spells in his homeland, 30-year-old Bates has club experience in Belgium, England and Germany, with most appearances coming at Mechelen.
Luke Graham, Jack Hendry and Ryan Porteous are the other central defenders in Sebastien Pocognoli’s squad, though left-back Kieran Tierney can also operate in the head coach’s preferred back three.
Brondby’s Binks won his first three caps during Scotland’s opening four Nations League fixtures, in which they picked up four points.
North Macedonia, who travel to Hampden on Friday, have no points in the section, with Slovenia three points better off than Scotland and Monday’s hosts Switzerland on maximum points.
