Scotland striker Ross McCormack has withdrawn from the national squad for this week's international fixture due to illness.

The Leeds United forward was called up to the team to face Estonia at the Pittodrie Stadium on Wednesday.

The national set-up, who are due to play their first game since Gordon Strachan was appointed as manager, have confirmed that McCormack will return to the Championship club.

Scotland managed to clinch a win over Luxembourg in their last friendly in November.
