Southampton winger Stuart Armstrong suffered an injury during his country's 3-0 defeat against Belgium.
The midfielder came off and was replaced by Ryan Fraser during the first half of the Euro2020 qualifier.
It is unclear if Armstrong suffered a serious injury or the substitution was a precaution.
The Scottish were disappointed in the outcome of the game, getting handed a lesson by the superior Belgians.
Romelu Lukaku scored twice in the game, with Kevin De Bruyne netting the third goal.
