Aberdeen, Motherwell and Rangers will find out their Europa League second qualifying round opponents on Monday.
All three sides are seeded, with Rangers facing either Bosnians Borac Banja Luka, Servette of Switzerland, or Gibraltar’s Lincoln Red Imps.
Motherwell play Swedes IFK Goteborg, B36 Torshavn of the Faroe Islands, or Northern Irish side Coleraine.
Aberdeen take on Welsh outfit Bala Town, Viking of Norway, or Luxembourg’s Progres Neiderkorn.
The draw starts at 11:00 BST, with the one-legged ties played on 17 September.
The trio will be joined by Celtic in Tuesday’s third qualifying round draw.
However, two of the 10 teams dropping down from the Champions League second qualifying round will be given a bye to the play-off round.
If Neil Lennon’s side are not one of those, they will be seeded in the champions side of the third round draw, as will Rangers in the non-champions route.
However, Aberdeen and Motherwell could be matched with daunting opposition in ties played on 24 September.
