Roberts has been struggling with a heel problem and the playmaker has not trained this week.
Matty Brown will miss out after sustaining a hamstring injury while fellow central defender Ian Evatt continues to build up his match fitness following a lengthy spell out after knee surgery.
Evatt, who will be captain when he regains fitness, got 70 minutes under his belt in a practice match this week and is scheduled for another run out against Sheffield Wednesday next week.
