Huddersfield striker Jordan Rhodes will be named in the Scotland squad to face Australia after being left out of the under-21 pool.
Rhodes, who made his full Scotland debut as a late substitute against Cyprus in November, will be among the players Craig Levein selects for the August 15 friendly at Easter Road.
Scotland Under-21s play Belgium at East End Park the previous night and head coach Billy Stark named his squad with defender Murray Wallace the only Huddersfield player present.
Blackburn and Fulham have both reportedly targeted 22-year-old Rhodes, who scored 48 goals last season for Town and Scotland Under-21s.
Stark, who also called up Stoke midfielder Jamie Ness, said: "That 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. He is looking forward to playing in the Championship. The Scotland path has been open to him before in Cyprus. He has been exceptional at under-21 level."
Ness returns after injury wiped out the vast majority his final season with Rangers. But he had already made enough of an impression in his 16 first-team games to prompt Stoke to move when the Ibrox club went into liquidation.
Stark said: "Jamie has been involved with us through the youth teams so I know all about him. It has been really frustrating for him and also for us that he has had a number of injuries and never been able to get a full run. But he has had a full pre-season behind him and played over in the States with Stoke."
Stark is looking to use the Belgium game to sharpen his side up for two European Under-21 Championship qualifiers against Luxembourg and Austria in September with a play-off spot in reach.
