Matchday two of the Betfred Cup takes place this midweek, with 15 ties across the eight groups on Tuesday and one on Wednesday.
Peterhead, Brechin City, Dunfermline Athletic, Alloa Athletic, Stenhousemuir, East Stirlingshire, Edinburgh City and Berwick Rangers all make their first appearances in this season's revamped competition after sitting out at the weekend.
St Mirren and Ayr United - who meet in Paisley - are among the clubs looking to make it two wins out of two, as are Rangers, who welcome Annan Athletic to Ibrox.
Each of the 40 teams will play four matches, with the eight group winners and four best runners-up progressing to the last 16 of the competition.
All drawn games go straight to penalties, with the winners earning a bonus point.
