(Current league positions in brackets)
Saturday, September 15
Dundee (10) v Motherwell (1)
Dundee are without defender Davide Grassi after he underwent a knee operation that will sideline him for six weeks. Left-back Brian Easton and midfielder Mark Kerr are both in contention after joining the club but skipper Stephen O'Donnell and Nicky Riley (hamstring), Kevin McBride (foot), Carl Finnigan (knee), Mark Stewart (knee), and Jamie McCluskey (Achilles) are all still out.
Well have close to a full squad, with Stevie Hammell and Simon Ramsden returning from hamstring injuries, Shaun Hutchinson back from suspension and others having shaken off knocks that troubled them before the international break. Steven Saunders is the only player missing as he recovers from knee surgery.

Hibernian (3) v Kilmarnock (8)
Left-sided defender Ryan McGivern, signed on loan from Manchester City, could make his Hibs debut after Sean O'Hanlon was allowed to depart. Honduras midfielder Jorge Claros could also be involved despite a busy international break, while imminent signing Tom Taiwo is unlikely to feature.
Cillian Sheridan could make his Kilmarnock debut if manager Kenny Shiels rules him sharp enough. Gary Harkins could be involved following a facial injury but Jereon Tesselaar (hamstring), Cammy Bell (wrist), Garry Hay (knee) and Paul Heffernan (collarbone) remain sidelined.

Niall McGinn returns to the Aberdeen squad after an ankle injury. Gary Naysmith (hamstring) and Rob Milsom (knee) are out but the latter is due to resume full training next week.

St Johnstone (12) v Celtic (2)
St Johnstone manager Steve Lomas is "keeping his fingers crossed" that no more players are taken ill before tomorrow's lunchtime kick-off. The Northern Irishman had seven players missing with a virus yesterday and while he was reluctant to say how many had recovered today, he is hoping that "not too many are missing." Defender Callum Davidson has a knock and he too will be assessed in the morning.
Celtic skipper Scott Brown (hip) will make his first SPL start of the season and defender Charlie Mulgrew is back after an Achilles injury. Forward Georgios Samaras (elbow) is out and defender Efe Ambrose has yet to return from international duty with Nigeria but strikers Lassad Nouioui and Miku and goalkeeper Lubos Kamenar are in contention.

St Mirren (6) v Hearts (7)
St Mirren manager Danny Lennon is hoping Kenny McLean and Paul Dummett, who are struggling with slight knocks, will be fit. Long-term casualties Darren McGregor and Grant Adam both remain on the sidelines.
Ryan Stevenson could make his first Hearts start since returning to Tynecastle in the transfer window. Manager John McGlynn reports no ill-effects of the international fixtures, with defenders Andy Webster, Marius Zaliukas and Ryan McGowan set to return.
