Kilmarnock have been drawn against Belgian side Cercle Bruges in the Europa League second qualifying round.
Derek McInnes’ side will host the first leg on 25 July before visiting Belgium a week later.
Stephen Robinson’s St Mirren will find out their Europa Conference League opponents when the draw is made at 13:00 BST.
Cercle Bruges are in European competition for only the fourth time and the first since reaching the Europa League third qualifying round in 2011, when they lost to Anorthosis Famagusta.
Led by 41-year-old Miron Muslic, the Bosnian who stepped up from assistant in 2022, they finished fourth in the Belgian Pro League last season.
