Dundee United have been drawn to face Queen of the South in an all-Championship clash in the semi-final of the Irn Bru Cup.
St Mirren, who are currently bottom of the division and still without a league win so far this season, will play Welsh Premier League leaders The New Saints.
Mark Durnan scored as United beat Dunfermline 1-0 on Saturday to book their spot in the last four, while Stephen Dobbie scored twice as Queen of the South beat Alloa in the quarter-finals.
St Mirren overcame Ayr United 2-1, while The New Saints hammered Livingston 3-0 to set up the meeting with Jack Ross's side.
The New Saints are playing in the competition for the first time after it was expanded this season to include two sides from the Welsh Premier League and the Northern Ireland Football League.
Semi-final ties are scheduled for the weekend of February 18/19, with the final on the weekend of March 25/26.
