Andrew Considine is doubtful for Aberdeen.
Dons boss Craig Brown will make a late decision on Considine, who damaged a knee in training to add to a lengthy injury list.
Paul Hartley (knee), Rory McArdle (shoulder) and David McNamee (hamstring) remain out, along with long-term injury victims Yoann Folly, Darren Mackie and Fraser Fyvie, who has returned to training but will not yet be considered for selection.
Inverness forward Richie Foran is suspended.
Foran begins a two-match ban but Ross Tokely and Stuart Duff return from suspension.
Jonny Hayes (ankle), David Proctor (hamstring), Dani Sanchez (hand) and Graeme Shinnie (stomach) remain out.
Aberdeen (from): Langfield, Diamond, Smith, Aluko, Considine, Vujadinovic, Milsom, Vernon, Blackman, Maguire, Magennis, Howard, Young, Pawlett, Jack, Paton, Anderson, Robertson, Low.
Inverness (from): Esson, Innes, Munro, Hogg, Gillet, Doran, Odhiambo, Tokely, Duff, Rooney, Duncan, MacDonald, Ross, Cox, Morrison, Sutherland, Tuffey.
