Craig Conway and David Marshall have been called up to the Scotland squad for their World Cup qualifiers against Belgium and Macedonia in September.
Former City plaket Kenny Miller, who scored for Scotland last week at Wembley, has announced his retirement from international football.
Scotland manager Gordon Strachan said: "Kenny is a talented player who absolutely gave the best of himself when he was on Scotland duty.
"In my time as national coach it has been a pleasure to have a player with his ability and experience in the squad.
"He has come to this decision to help prolong his club career, and feels that this is the best time to bow out.
