Clydesdale Bank Premier League
12:30 St Mirren vs Celtic
Aiden McGeady is out of Celtic's SPL clash with St Mirren on Saturday through injury.
The Republic of Ireland midfielder picked up an ankle knock in the Co-operative Insurance Cup win at Falkirk on Wednesday night but the injury is not as bad as first feared.
Pat McCourt and Niall McGinn will battle it out to replace McGeady in the side.
New signing Zheng Zhi will not be included as manager Tony Mowbray returns to his first-choice line-up after making eight changes for the cup game at the Falkirk Stadium.
St Mirren defender Lee Mair is suspended for the visit of the SPL leaders.
Chris Innes will make his debut after Mair was sent off late in the 1-0 defeat by Aberdeen.
Mo Camara has undergone knee surgery while Steven Robb (groin) and Chris Smith (knee) are still absent.
15:00 Falkirk vs Kilmarnock
Bottom club Falkirk welcome fellow strugglers Kilmarnock to the Falkirk Stadium looking to climb off the foot of the table.
Eddie May's men have just two points to show from their opening five fixtures, while visitors Killie have fared little better with only four points on the board.
Scott Arfield is out of the Falkirk squad for the Clydesdale Bank Premier League clash.
The midfielder aggravated the knock which kept him out of last weekend's goalless draw at Hamilton.
However, Burton O'Brien, Jackie McNamara and Thomas Scobbie will all return to the starting line-up.
Killie news
Craig Bryson is a major doubt for Kilmarnock after the midfielder picked up a groin injury in the midweek Co-operative Insurance Cup defeat by St Mirren.
Simon Ford (knee) and Tim Clancy (elbow) are still out while Manuel Pascali is suspended after being sent off last week against Rangers.
Allan Russell and Jamie Fowler come into contention after returning from long-term knee and hernia injuries respectively.
15:00 Hearts vs Hamilton
Hearts can move three points clear of Hamilton in the SPL table with success at Tynecastle on Saturday.
Home trio Andrew Driver, Lee Wallace and Gary Glen have all been passed fit for the clash.
Driver missed Wednesday's Co-operative Insurance Cup third-round win over Dunfermline after complaining of discomfort in his knee while Wallace and Glen had to be substituted in the second half after picking up knocks.
David Templeton is back in contention after fully recovering from foot surgery but Laryea Kingston is likely to miss out again even though manager Csaba Laszlo revealed he could soon be back with the first-team squad.
Hamilton news
Hamilton will be without Derek Lyle for the trip to Edinburgh after the striker was ruled out for the rest of the season.
Lyle underwent cruciate ligament surgery on Thursday after suffering the injury in the opening moments of last Saturday's goalless draw with Falkirk.
The 28-year-old joins fellow long-term casualties James Gibson (knee) and Alex Neil (hip) on the sidelines.
15:00 Motherwell vs Hibernian
Motherwell and Hibernian are currently locked together in the SPL standings and go head-to-head this Saturday.
Well sit fourth at present, going unbeaten through their opening five fixtures of the 2009/10 campaign.
Hibs have tasted defeat twice this term, in their last three games, but they occupy third spot by virtue of a having scored more goals this season than their weekend opponents.
Motherwell striker John Sutton should return to Jim Gannon's first-team plans.
Sutton missed the 3-2 cup win over Inverness in midweek after picking up knock in the victory over Dundee United but is expected to be fit.
But Shaun Hutchinson (ankle) and Paul Slane (calf) are unlikely to return until after the October international break.
Hibernian have no fresh injury concerns ahead of their trip to Fir Park.
However, boss John Hughes is pondering changes following Tuesday night's Co-operative Insurance Cup third round defeat by St Johnstone.
He must also decide whether to include Kevin McCann in his squad now the injury-plagued full-back is fully fit after a hamstring problem.
15:00 Rangers vs Aberdeen
Rangers welcome Aberdeen to Ibrox determined not to lose any further ground in the fledgling Scottish Premier League title race.
Walter Smith's side, who are two points adrift of Celtic, have been dealt a blow with the news Sasa Papac is set to miss the fixture.
The full-back is a doubt with a hamstring strain and is unlikely to be risked ahead of next week's UEFA Champions League game against Sevilla.
Kyle Lafferty remains on the sidelines with a knee injury, while Pedro Mendes is suspended for the visit of the Dons.
Dons team news
Aberdeen will be without Davide Grassi after he was ruled out for a minimum of six weeks.
Grassi suffered a fractured cheekbone during the midweek Co-operative Insurance Cup defeat to Dundee and is set to have an operation this weekend.
Sone Aluko is with the Nigeria squad at the Under-20 World Cup in Egypt, while Zander Diamond remains on the sidelines with a foot injury.
15:00 St Johnstone vs Dundee Utd
St Johnstone host rivals Dundee United on Saturday eager to get their first home win of the season.
Saints have drawn both their fixtures at McDiarmid Park this term while United's away record mirrors that feat.
St Johnstone have one injury worry, but boss Derek McInnes refused to disclose the identity of the player, who is doubtful for the match.
Kevin Rutkiewicz and Graeme Smith will take another step to full fitness by playing in a closed-door game next Tuesday after recovering from knee and thigh injuries respectively.
However, Peter MacDonald (hamstring) Kevin Moon (groin) and long-term injured Andy Jackson are all still out.
Damian Casalinuovo is in line for a quickfire debut for Dundee United in Saturday's Tayside derby meeting.
The Argentinian striker has only just returned to Tannadice following a month's loan at Raith Rovers and his goalscoring exploits at Starks Park have propelled him into contention for the trip to McDiarmid Park.
Casalinuovo signed over the summer after impressing during the team's pre-season tour of Ireland but was immediately ruled out of action when he dislocated his shoulder before the season began.
Boss Craig Levein's hand may be forced because of a mini-injury crisis which has left doubts hanging over several players.
Morgaro Gomis is likely to be ruled out with a calf injury and could be joined in the stand by Danny Cadamarteri, who has been suffering from a dead leg.
One plus for the Tangerines is that Scott Robertson looks like making it after returning to training.
With having so many uncertainties surrounding his line-up Levein will break with his own tradition and name his side on Saturday morning rather than 24 hours earlier.
