The group stage of the 2021/22 Premier Sports Cup begins on Friday evening, with Kelty Hearts v Dundee United live on Premier Sports.
Also this evening, Edinburgh City - who will be playing the majority of their home matches on a Friday this season - host Hamilton Accies.
Saturday's fixtures include Peterhead versus Heart of Midlothian at Balmoor and Brechin City against last season's runners-up Livingston at Glebe Park.
The group stage involves 40 clubs - the 37 SPFL clubs from 2020/21 who did not qualify for Europe plus Brora Rangers (Highland League champions), Kelty Hearts (Lowland League champions) and East Kilbride (Lowland League runners-up).
Clubs are awarded the usual three points for a win but all drawn games in the group stage go straight to penalties - the shoot-out winners receive a bonus point. ie three points for a win, two points for a shoot-out win and one point for losing on penalties.
If clubs are level on points at the end of the group stage, the criteria for separating them is 1) goal difference, 2) goals scored, 3) away goals scored, 4) matches won, 5) away matches won, 6) drawing of lots.
The eight group winners and three best runners-up progress to the second round, where they are joined by the five clubs competing in European competitions - Rangers, Celtic, Hibernian, Aberdeen and St Johnstone, who are also the cup holders.
The seeded teams in the last 16 will be the five European entrants and the three group winners with the best records.
The tournament reverts to a traditional knock-out format from the second round onwards, with ties decided by extra time and penalties if the scores are level after 90 minutes.
