HEART OF MIDLOTHIAN v ST MIRREN - Saturday 15:00
Andy Webster is suspended for Hearts. The Jambos defender is sidelined after being sent off in the defeat against Dundee at Dens Park last week. Fellow centre-back Danny Wilson is still struggling with a thigh injury but may still feature.
St Mirren manager Danny Lennon has no fresh injury worries. That means the Buddies boss could name a similar squad to the one who drew with Hibernian last week. The Paisley club will again be without suspended skipper Jim Goodwin.
DUNDEE UNITED v ST JOHNSTONE - Saturday 15:00
Dundee United are without suspended full-back Barry Douglas after an appeal against his dismissal in the defeat to Ross County was rejected. However, striker Johnny Russell is in contention to start after recovering from his broken leg. Richie Ryan and Keith Watson are struggling with knocks and defender Gavin Gunning remains sidelined by a knee injury.
St Johnstone boss Steve Lomas is sweating on two of his midfielders but hopes to have Murray Davidson back in his line-up. The Europa League-chasing Perth men may have to do without on-loan Newcastle youth Mehdi Abeid due to a thigh strain, while Irishman Patrick Cregg is struggling after jarring his knee. But Davidson has recovered from an ankle knock and returns to Lomas' squad after missing last week's win over Inverness. Long-term absentees David Robertson and Jamie Adams, meanwhile, remain on the sidelines.
INVERNESS CT v MOTHERWELL - Saturday 15:00
Inverness right-back David Raven is suspended. The former Liverpool player was sent off early on in last week's defeat by St Johnstone. Goalkeeper Ryan Esson and defenders Gary Warren and Simon King remain out.
In-form Motherwell again have a full squad. Manager Stuart McCall is likely to field the same team that beat both Dundee United and Celtic 3-1 in recent weeks. Motherwell are looking for a clean sweep over their closest rivals for second place, with PFA Scotland player of the year nominee Michael Higdon looking to add to his six-goal tally against Inverness this season.
ROSS COUNTY v CELTIC - Sunday 12:00
Ross County are set to name an unchanged squad. Defender Branislav Micic remains out with a dislocated shoulder. Goalkeeper Mark Brown is also on the sidelines with a fractured hand.
Celtic will be much-changed again for their clash with Ross County in Dingwall. Georgios Samaras, Charlie Mulgrew, Gary Hooper and Fraser Forster will all be rested with Emilio Izaguirre also set to be left out while Kris Commons, Joe Ledley, Efe Ambrose and Kelvin Wilson return after they were given the week off by manager Neil Lennon following their title triumph. Lassad Nouioui (calf) and Scott Brown (abductor) remain on the sidelines and while Adam Matthews (hamstring) and James Forrest (knock) have returned to training, they are not yet ready to play.
DUNDEE v ABERDEEN - Sunday 15:00
Dundee midfielder Gary Harkins has recovered from a rib injury which forced him to miss last weekend's win over Hearts. However, they are without Nicky Riley after he received a two-match ban for his red card against the Edinburgh side. Dundee are still without Stephen O'Donnell (knee) and Jamie McCluskey (Achilles).
Aberdeen manager Derek McInnes will make a decision on the fitness of captain Russell Anderson. The defender did not train today after missing last weekend's win over Kilmarnock with a hamstring injury but will do some light training tomorrow with a view to playing at Dens Park. Defender Andrew Considine (broken leg) and midfielder Chris Clark (broken ankle) are both out for the rest of the season.
KILMARNOCK v HIBERNIAN - Sunday 15:00
Kilmarnock are boosted by the return of Rory McKenzie. The forward has missed the last couple of matches through illness but will be back in contention for Sunday's clash at Rugby Park. Rory McKeown, Manuel Pascali and James Dayton are still on the sidelines.
Hibernian boss Pat Fenlon has no injury worries. The William Hill Scottish Cup finalists sent Killie spinning in the quarter-finals with a 4-2 win thanks to a hat-trick from striker Leigh Griffiths and the 27-goal Scotland cap will hope to continue his hot streak this weekend. The on-loan Wolves man - who will return to Molineux in the summer - is just one behind the 28 netted by Steve Cowan in season 1985/86 and with four games of the season remaining, he could become the first Easter Road attacker to net 30 since Alan Gordon and Jimmy O'Rourke both reached that mark in season 1972/73.
