Dons duo Zander Diamond and Yoann Folly will be given every opportunity to prove their fitness ahead of the quarter-final clash.
Defender Diamond and midfielder Folly injured their ankles in last Saturday's 4-2 win over Hibernian at Pittodrie, while defender Andy Considine is struggling after injuring a knee in the warm-up at the weekend.
Nikola Vujadinovic missed the Hibs match with a hamstring injury and remains absent, while Peter Pawlett (broken toe) and long-term casualty Fraser Fyvie are out.
Aberdeen (from): Howard, Diamond, Considine, McArdle, Folly, Aluko, Hartley, Jack, Vernon, Velicka, Mackie, Maguire, Fraser, Ifil, Young, Paton, Magennis, Langfield.
