The 20-year-old is hoping to make his fifth appearance for Billy Stark's Under-21s side when they take on Luxembourg at St Mirren's Paisley Park on Monday, March 25.
The Scots will play Norway in a behind-closed-doors friendly at the same venue four days earlier.
Wallace, a left-footed central defender, has made six appearances for Huddersfield since arriving from Falkirk for an undisclosed fee in the January 2012 transfer window.
He is one of only eight English-based players included in Stark's 22-man squad.
