Partick v Dundee Utd preview

Chris Erskine is unable to play against his parent club while Mark Kerr and Ross Forbes left Firhill this week.
Isaac Osbourne and Sean Welsh remain long-term absentees with ankle and groin problems respectively while Kallum Higginbotham could feature despite needing six stitches in a knee injury last weekend.
Travelling Dundee United have added 20-year-old on-loan defender Curtis Good to their squad.
But Gavin Gunning and Brian Graham are unlikely to return due to knee concerns.
