Falkirk right-back Kieran Duffie has been overlooked by Scotland under-21s chief Billy Stark.
However, Murray Wallace, who moved to Huddersfield Town in the summer after a season in Falkirk’s first team, has been selected for the match in Dunfermline later this month.
Both defenders were included in an under-20s squad which travelled to Holland in May, and it is the first call for 19-year-old Wallace who established himself as Falkirk’s first choice central defender beside Darren Dods last term.
The omission of Falkirk’s 20-year-old right back is likely to frustrate Bairns chief Steven Pressley who questioned the Scotland under-21 squad for a match with Holland in February.
He said: “It’s quite amazing when you look at the under-21s squad there’s no Falkirk players in there. Do they just take guys from reserve teams?
“I find it remarkable that I have players who’ve featured in more than 30 games and I’m seeing names in the under-21s squad who haven’t played in a first team for months.”
Billy Stark countered a day later saying he was aware of the likes of Duffie and Wallace who were both overlooked.
“Falkirk have got players who are well on our radar, they have just not been picked for this one,” he said.
The under-21 squad for Belgium on August 14 has only three players - Wallace, Hull’s Thomas Cairney and Gregg Wylde of Bolton - who play outwith the top leagues in England and Scotland.
