Morton and St Mirren meet at Cappielow in a rearranged Ladbrokes Championship fixture on Tuesday evening, kick-off 7.45pm.
Jim Duffy's men go into the game on the back of three straight league wins while Saints are looking for their first Championship victory of the season.
St Mirren are unbeaten in the last 12 derbies since Morton won 5-1 at Love Street in April 1999, thanks to a hat-trick from Kevin Thomas and a double from Keith Wright.
It was 1-1 when the sides met in Paisley on the opening day of the season, with John Sutton equalising late on after Thomas O'Ware had opened the scoring.
