Tonight's fixtures are the first of two key rounds before a break for the Scottish Cup quarter-finals.
Rangers are live on Sky Sports as they travel to St Johnstone with a number of injury issues. It is something which has also hampered Saints in their pursuit of Premiership safety. Giovanni van Bronckhort’s men will be looking to keep the on rivals Celtic after missing the chance to make ground on their rivals at the weekend.
Celtic, meanwhile, host a St Mirren side under new management with Stephen Robinson in the dugout. The Buddies are one of seven teams not only in contention for the top six but European football. Livingston host Dundee United as well as Motherwell face Ross County in fixtures which could change the dynamic of the middle of the league.
Hibs will be expected to strengthen their position in fourth place as they visit bottom of the table Dundee, while Aberdeen will be hoping to keep up their unbeaten run against Hearts at Tynecastle Park.
The Jam Tarts are the only side in the league who don't appear to have any direct rivals in the league as they sit comfortable in third place with an 11-point buffer over Hibs. Wins over the Dons and then Dundee United on Saturday would all be secure the best of the rest tag.
