Fitness and form guide for weekend's Premiership matches
Five matches will be played on Saturday, while Hearts should host Partick Thistle on Sunday.
Celtic look to extend their lead at the top of the Scottish Premiership when they head north to take on Ross County in-front of a sell-out crowd.
The side currently clinging to Brendan Rodgers' unbeaten Hoops' coat-tails, Aberdeen, host League Cup finalists Motherwell later on Saturday, while Graeme Murty's Rangers take on Hamilton at Ibrox.
St Johnstone travel to Edinburgh to take on Hibs and Dundee visit Kilmarnock, before Hearts are expected to round off the weekend against Partick Thistle at Tynecastle.
