A look ahead to the weekend action across the four divisions of the SPFL:
Aberdeen go into their home game against St Johnstone with a four-point lead despite seeing their perfect start come to an end with a defeat at Inverness CT last weekend. Second-placed Celtic go to Hamilton Accies, who are fourth, on Sunday in a game that is live on BT Sport at 12.30pm. Hearts recently knocked Kilmarnock out of the League Cup at Rugby Park and now welcome Gary Locke's team to Tynecastle on league business. Bottom club Partick Thistle will leapfrog Dundee United if they can claim their first win of the season when the teams meet at Firhill, with Dave Bowman in caretaker charge of the visitors. Interim Motherwell boss Stephen Craigan takes the Steelmen to Dundee and it's derby day in the Highlands - Ross County are three places and five points ahead of Caley Thistle as they welcome their rivals to Dingwall.
It's first against second at Ibrox as leaders Rangers bid to make it nine wins out of nine when they face a Falkirk team who are nine points behind with a game in hand. Raith Rovers are up to third place on the back of an outstanding home record and welcome Morton to Stark's Park. Queen of the South have the chance to move above Hibernian and into the top four but will need to beat Alan Stubbs' side at Palmerston to do so. St Mirren are at home to bottom club Alloa and Dumbarton meet Livingston at the Cheaper Insurance Direct Stadium.
Ladbrokes League 1
Leaders Ayr United took 10 points out of a possible 12 during September and will be hoping to maintain their good form when second-bottom Cowdenbeath visit Somerset Park. Dunfermline are just a point behind Ian McCall's men as they prepare to face Albion Rovers at East End Park, with the Coatbridge club outside the top four only on goal difference following a good start to life in a higher division. Forfar, in third spot, go to Peterhead and fourth-placed Airdrieonians entertain Stranraer. Bottom club Brechin City are chasing a third straight win when they travel to Ochilview to play Stenhousemuir.
Ladbrokes League 2
Half the division are separated by just two points, with East Fife, who lead on goal difference, at home to a Stirling Albion side who they also meet in the Scottish Cup later this month. Queen's Park, in second spot, are chasing a fourth straight win when they welcome Montrose to Hampden. Arbroath have recovered well from a poor start and go into their home match with Annan having won three on the trot. Elgin City and Clyde are separated only by goal difference ahead of their meeting at Borough Briggs while Berwick Rangers are up against bottom club East Stirlingshire at Shielfield.
