Captain Paul Hartley could return for Aberdeen.
Hartley has missed the Dons' last five matches with a knee injury, but manager Craig Brown is set to make a late decision on whether to include the former Celtic and Hearts midfielder.
Rory McArdle (shoulder) and David McNamee (hamstring) are out along with long-term injury victims Yoann Folly, Darren Mackie and Fraser Fyvie.
Celtic manager Neil Lennon has a near full squad to choose from.
Daniel Majstorovic has resumed training after a toe injury but may not be rushed back for the Hampden clash.
Andreas Hinkel is also in training following a cruciate ligament injury but is not ready to return to match action.
Aberdeen (from): Langfield, Diamond, Smith, Aluko, Considine, Vujadinovic, Milsom, Vernon, Blackman, Maguire, Magennis, Howard, Young, Pawlett, Jack, Paton, Anderson, Hartley.
Celtic (from): Forster, Loovens, Cha, Mulgrew, Izaguirre, Ljungberg, Commons, Kayal, Ki, Ledley, Stokes, Hooper, Maloney, Forrest, Zaluska, Rogne, Wilson, Samaras, Brown.
