Anthony Ralston has won his first Scotland call-up.
Ralston has made 23 appearances for Celtic this season after seizing his chance under Ange Postecoglou.
The 22-year-old comes in to the squad after Nathan Patterson picked up a suspension during Friday’s win over Moldova which sealed a play-off place.
Motherwell’s Stephen O’Donnell is the other right-back in the squad but he is among eight players who are one yellow card away from missing the play-off semi-final in March.
Scotland are looking to boost their chances of sealing a home semi-final when they host Group F winners Denmark.
