Linfield will travel to face holders Dundee United while The New Saints host Elgin City in the third round of the Scottish Challenge Cup.

The other non-Scottish team left in the competition, Crusaders, are away to Highland League side Cove Rangers.

Falkirk host Dunfermline Athletic in the only all-Championship tie.

It is the second year in which non-Scottish clubs have been involved in the competition for teams outside the Scottish Premiership.

Northern Irish and Welsh teams took part last season, while sides from the Republic of Ireland made their debut in the current competition.

Welsh champions TNS, who reached the semi-final last season, losing to St Mirren, progressed to the third round by beating Livingston after a penalty shoot-out.

Irish League champions Linfield also made their debut in the competition last term, when they lost to Queen of the South, and beat Lowland League outfit Spartans to reach this season's third round.
