Highlights of the weekend's action in the SPFL including action from Friday night's Tayside derby between St Johnstone and Dundee. On Saturday, Aberdeen entertain Ross County, looking to avenge their 2-0 defeat from earlier in the season and Hearts are away to Motherwell. Bottom of the table Dundee United welcome Hamilton Accies to Tannadice and Kilmarnock face Partick, a win for either side would be priceless in keeping them away from danger at the bottom. On Sunday, champions and league leaders Celtic make the long trip north to face cup holders Inverness CT in the lunchtime kick-off.
