Zander Diamond is injured and Charlie Mulgrew suspended for the game, from which the Dons need a point to mathematically secure their survival.
Sone Aluko remains a doubt, while Gary McDonald (hamstring) is likely to be out for the rest of season, joining Peter Pawlett (knee) and Andrew Considine (hip), who are long-term absentees.
Saturday's match kicks off at 12pm.
Aberdeen (from): Langfield, Foster, Kerr, Fyvie, Mackie, Paton, Ifil, Duff, Nelson, Young, Marshall, Grassi, Aluko, Jack, Grimmer, Shaughnessy, MacLean, Robertson.
