Aberdeen v Hearts
Jamie Hamill returns to the Hearts squad for the first time in almost a year. The Jambos right-back has been out since rupturing his cruciate knee ligament during a indoor training session last April. However, Gorgie boss Gary Locke has confirmed the former Kilmarnock player is back in contention.
Aberdeen hope to have Ryan Jack and Clark Robertson fit.Jack has resumed training after picking up an injury with Scotland Under-21s while Robertson is pushing for a return after an ankle injury. Longer-term casualties Gary Naysmith, Isaac Osbourne, Andrew Considine and Chris Clark remain out.
Dundee v Motherwell
Dundee midfielder Mark Kerr is available again after five months out with a knee injury. But defender Gary Irvine begins a two-match suspension following his red card in the Dundee derby. Stephen O'Donnell (knee) and Jamie McCluskey (Achilles) are still out, while Steve Simonsen will make his home debut in goal.
Motherwell should have an unchanged squad for the game. Central midfield pair Keith Lasley and Nicky Law went off with knocks in the 4-1 win over Hibernian two weeks ago but both are expected to make the Dens Park trip. Defender Fraser Kerr is the only major cause for concern with a back injury.
Hibernian v Inverness
Hibernian manager Pat Fenlon could have Tim Clancy back. The former Kilmarnock defender has recovered from the hamstring complaint which has kept him out for almost two months. Stopper Paul Hanlon has shaken off his hip injury but will not feature, while defender Alan Maybury is suspended after picking up his sixth booking of the season in the 4-1 defeat at Motherwell before the international break.
Inverness will be without goalkeeper Ryan Esson and centre-back Gary Warren. Both are out for up to six weeks - Esson with a torn thigh muscle and Warren with lateral ligament damage in his knee. Chris Hogg is not yet ready to step in after a year out with a knee injury but Graeme Shinnie returns from suspension. Simon King remains out.
Ross County v Kilmarnock
Ross County are without Ivan Sproule and Stuart Kettlewell. Sproule has not recovered from the injury that forced him off against Inverness while Kettlewell is suspended. Goalkeeper Mark Brown remains out with a broken hand but captain Richard Brittain returns from suspension.
Kilmarnock will be without the suspended Paul Heffernan. Cillian Sheridan is doubtful with a knock, but could still make the trip to Dingwall, while skipper Manuel Pascali and Rory McKeown remain on the sidelines.Rory McKenzie and Ross Barbour are back in contention after injury.
