The Staggies need a maximum of four points to clinch the title so a win against Ian McCall's men followed by closest challengers Dundee United failing to beat Inverness CT in the Highland capital on Saturday would see them promoted.
Ian McCall's men are third in the table, ahead of Inverness CT on goal difference, with a game in hand at home to Partick Thistle on Tuesday.
The teams drew 3-3 at Somerset Park in December, with Ross County winning the two meetings in Dingwall this season.
