Celtic require a maximum of four more points to retain the title. Neil Lennon's team could get over the line this weekend if they beat Kilmarnock at Celtic Park on Saturday lunchtime and Rangers then drop points to Aberdeen at Ibrox on Sunday. Both games are live on Sky Sports.
Ross County are just one point away from a return to the top flight so will be champions if they avoid defeat to Queen of the South in Dingwall on Friday night, live on BBC Scotland at 7.05pm. Closest challengers Dundee United are at home to Falkirk on Saturday - Robbie Neilson's men are six points behind the Staggies and 18 goals worse off.

Arbroath clinched the title with a 1-1 draw at Brechin City on April 13 and will be presented with the trophy after their final home game of the season against Dumbarton on May 4. Dick Campbell's team are away to Airdrieonians this Saturday.
Ladbrokes League 2
Peterhead have a four-point advantage over Clyde with two matches remaining. The Blue Toon will therefore be champions if they beat Stirling Albion at Balmoor on Saturday - Jim McInally's men have won all three league meetings between the teams this season. A draw, or even a defeat, could still see Peterhead over the line, depending on the outcome of Clyde's game against Queen's Park at Broadwood.
