Alex Petkov has received another call-up to the Bulgarian under-21 squad.
The centre-back, who is currently on loan at Clyde, will join up with his countrymen next week to face Estonia and Russia.
The Lions take on their opposition in 2021 Under-21 Euro qualifiers. They face Estonia away from home on September 5th, and take on Russia at home on the 10th.
As a result, he will miss Clyde's next fixture on Saturday when they are due to play Forfar Athletic.
Petkov, who was named Reserve POTY last season, has started the last four consecutive games for the Bully Wee.
The Sofia-born defender, whose dad Milan played for Bulgaria, has four caps for the under-21s to date. He made his debut in March 2019, facing Bobby Burns' Northern Ireland.
