Jack Ross is forced to make two changes to the side that defeated East Fife in the Scottish Cup last weekend.
Jack Baird comes into the team in place of Gary MacKenzie who is suspended while Cammy Smith is cup-tied and replaced by John Sutton.
Academy player Conor O'Keefe takes a place on the bench after scoring twice for the U20s against Kilmarnock during the week.
We'll have all the action covered on Twitter and Facebook, while supporters out with the UK & Ireland can watch the match live on St Mirren TV.
