St Mirren v Brechin preview

St Mirren striker Steven Thompson is a doubt for the William Hill Scottish Cup clash against Brechin on Saturday.

Thompson is doubtful after going off with a hip knock during Tuesday's goalless draw at Ross County.

Skipper Jim Goodwin is suspended after being booked twice in the competition last season.

Long-term absentees Paul McGowan and Darren McGregor remain on the sidelines.
