Steve Clarke has been forced into a significant Scotland squad reshuffle after four players dropped out.

Celtic duo James Forrest and Greg Taylor are both out of contention to face Poland and Portugal with Robby McCrorie and Che Adams also not out of the squad.

As a result, Clarke has added three players to his pool ahead of the Nations League matches later this month. 

Rangers summer signing Connor Barron has been called into the national team with Josh Doig returning to the fold and Dundee goalkeeper Jon McCracken handed his first call-up.
