Winger brought into squad
Dundee United winger Gary Mackay-Steven has been called up for Scotland's forthcoming friendlies with the United States and Norway.
The Scots take on the USA on Friday before travelling for their friendly in Norway next Tuesday.
Celtic forward James Forrest is already a major doubt for manager Gordon Strachan having being withdrawn during their weekend victory at Ross County.
Former United winger Craig Conway has similarly been called up after impressing since joining Brighton on loan from Cardiff City.
