Manchester United midfielder Darren Fletcher has been ruled out of Scotland's friendly at home to Argentina next week.
The 24-year-old suffered a knee injury during United's 5-0 victory over Stoke City at Old Trafford on Saturday.
Fletcher was out for six weeks in March after sustaining knee ligament damage in Scotland's friendly against Croatia.
Scotland take on Argentina in Diego Maradona's first game in charge of the visiting side.
Fletcher, who has been a regular for United this season, would have been expected to start against Argentina at Hampden.
