The Ladbrokes Premiership resumes this weekend and the action gets under way with Ross County v Celtic on Saturday lunchtime.
The game at the Global Energy Stadium is live on BT Sport, kick-off 12.30pm, with the visitors looking to stretch their unbeaten domestic run to 64 games against a County side who have won their last two home games.
Aberdeen are three points back in second spot as they prepare to face Betfred Cup finalists Motherwell at Pittodrie. Derek McInnes' men were held to a 2-2 draw at Hamilton last time out while Stephen Robinson's men are aiming to push on after two recent defeats.
Third-placed Hibernian are on a run of four straight wins and take on a St Johnstone team who have slipped out of the top six after failing to score in any of their last six matches.
Rangers again have caretaker boss Graeme Murty in charge for the Ibrox meeting with Hamilton Accies. Rangers have beaten Hearts and Partick Thistle in their last two games while Accies are undefeated in their last three fixtures.
Dundee have dropped to the foot of the table following five straight defeats but will move level on points with Kilmarnock if they win at Dens Park. Killie have been revitalised under Steve Clarke and beat Hearts 2-1 at Murrayfield before the break.
Hearts are due to return to Tynecastle on Sunday when they play Partick Thistle.
There were no scheduled games in the Ladbrokes Championship, League 1 and League 2 due to the third round of the Scottish Cup but two matches have been slotted in.
Dundee United have the chance to move to the top of the Championship when they face Falkirk at Tannadice on Sunday. Csaba Laszlo's side are behind leaders St Mirren on goal difference and are looking to bounce back from an IRN-BRU Cup defeat to Crusaders. The Bairns are down in ninth place, with just one league win so far, and were knocked out of the IRN-BRU Cup by Inverness CT.
In Ladbrokes League 2, Cowdenbeath and Annan Athletic have brought forward their December 30 clash at Central Park to this Saturday. New boss Gary Bollan will be in charge of the Blue Brazil for the first time and a win would lift them off the bottom and above Edinburgh City. Victory for Annan would see them move to within four points of the play-offs.
