The duo missed the home goalless draw with Chelsea last weekend through a back injury and sickness respectively.
Improvement: Heskey has shown good form since Gerard Houllier took over
Central defender Richard Dunne is also available after being substituted in the early stages against the Blues with a cut ankle which required several stitches.
But striker Gabriel Agbonlahor and full-back Luke Young are again ruled out. Agbonlahor is still recovering from minor surgery to his groin while Young will be out of action for a further two weeks with a torn hamstring.
Villa (from): Friedel, Beye, Collins, Dunne, Warnock, Downing, Petrov, Reo-Coker, Ireland, Ashley Young, Carew, Guzan, Heskey, Delfouneso, Albrighton, Clark, Cuellar, Sidwell, Bannan, Lichaj.
