The side managed by Alex Weir are not having a good season as they sit 10th of the 12 clubs in the Scottish Premier League. In their most recent match The Buddies were held to a 1-1 draw at home by Aberdeen. St. Mirren were able to qualify for this stage by holding serve home over Motherwell in their 5th round replay by a score of 1-0.
The visiting Celtic were able to take over sole possession of first place in the Scottish Premier League with a midweek victory away to Kilmarnock by a score of 1-2 thanks to two goals from McDonald. That win gives them 63 points and they sit 3 ahead of 2nd place Rangers. Gordon Strachan's side were winners at home to Queen's Park in the 5th Round and a win in this match would keep their dream of doing the double alive.
