St Mirren's Craig Reid back from ban for Morton clash
St Mirren welcome Craig Reid back from suspension when Morton visit in the Scottish Championship.
However, a knee injury keeps Jason Naismith out and Alan Gow is missing due to an ankle problem. Keith Watson and Jaison McGrath are both injury doubts for a game that manager Ian Murray reckons could change his side's season.
Murray explained: "Morton have done really well recently and sit 12 points clear of us in fourth place. However, if we can beat them and win our game in hand things will have tightened up.
"We lost 4-1 to Hibs in our last game but that was a harsh scoreline and there was a lot we can build on in the performance."
Morton, who have won four games in a row, will be on usual lines with knee injuries ruling out Frank McKeown and Peter MacDonald.
A hamstring problem sees Ricki Lamie remain absent and Romario Sabajo is still unavailable due to an ankle issue.
Manager Jim Duffy said: "There is a lot of extra attention on this game as it is a derby but I will settle for the same again from my players.
"First and foremost it is important that we keep on winning and gathering points in this league. Beating your local rivals is great for the fans however it only gets you the same three points."
