The Huddersfield striker has not been included in Billy Stark's Under-21 party and is likely to represent the full international side against Australia on August 15 at Easter RoadJordan Rhodes is expected to be named in Scotland's squad to take on Australia at Easter Road on August 15 after being left out of the Under-21 set up.
Fulham are thought to be eyeing a deal for the 22-year-old, who scored 40 goals for the Terriers last season.
And Scotland youth coach Billy Stark admitted his surprise that a deal had not already been struck for the former Ipswich man but insisted that the forward would remain loyal to the Galpharm Stadium.
Stark told reporters: "Last season will be difficult to repeat but in the previous two seasons he scored one in two, which is a fantastic average at any level.
"He is a goalscorer and a chance is a chance, and I don't have any doubts that if he gets a chance he will score in the Championship.
"You could maybe be a bit surprised he hasn't had a move after the season he has had. The window is open until August 31 so it still wouldn't surprise me.
"But he is such a grounded boy and he is not one who would be neglecting his work with Huddersfield waiting and wishing he was going to get a move to the English Premier League.
"He is looking forward to playing in the Championship."
