Liverpool defender Andrew Robertson was forced off with a shoulder injury in Scotland's Euros qualifying defeat in Spain.
He was substituted before halftime after a clash with Spain goalkeeper Unai Simon.
"We'll have a look and he'll go back to his club now," Scotland coach Steve Clarke told Viaplay after defeat in Seville.
"It always seems to happen when you lose one player in a position. We lose Kieran [Tierney] then Andy picks up a shoulder injury.
"We'll see how it is and how it settles down. Hopefully he's good for his club as soon as possible and ready to help us in November."
