Max Johnston and Aaron Hickey are the remaining right-back options for head coach Steve Clarke, with Sassuolo’s Doig boosting options at left-back.
Liverpool left-back and Scotland captain Andy Robertson has flitted between his natural position and left wing-back for the national team in recent years while Doig has a solitary senior cap.
Brentford’s Hickey, 23, is fit again after a near-two year absence following major hamstring problems.
When announcing the squad last week, Clarke said of Hickey: “He’s good to go. Whether he’s good to go 90 minutes over two games is a different conversation. We’ll manage him.”
Scotland begin their campaign in Copenhagen on Friday before travelling to Hungary to face Belarus on Monday, with both games to be shown live across the BBC.
