Ross County have a number of defensive injury worries.

Tom Grivosti had a slight hamstring problem following his first start in a year, Keith Watson is struggling with a knock, Carl Tremarco is trying to overcome a calf problem, Coll Donaldson (groin) is a doubt and Callum Morris is out along with midfielder Ross Draper (both calf).

However, right-back Connor Randall returns from suspension for the trip to Tannadice.
