Kilmarnock boss Kenny Shiels is likely to be without two important players for the visit of Hearts.
David Silva is definitely out with medial ligament damage while Zdenek Kroca is very doubtful with a virus.
Shiels' new signing, 29-year-old Slovenian Leon Panikvar, will not be included in the squad.
Ian Black is again suspended as Hearts bid to pick themselves up from their crushing defeat by Tottenham.
Black will serve the second of a two-match domestic ban in the only likely change from the squad defeated 5-0 in the Europa League by Spurs in a match which saw Andy Webster and David Obua return from injury.
Mehdi Taouil (groin) is likely to miss a return to Rugby Park, while Kevin Kyle (hip) and Calum Elliot (knee) remain long-term absentees.
Kilmarnock (from): Bell, Buijs, Kroca, O'Leary, McKeown, Dayton, Fowler, Kelly, Pascali, Harkins, Shiels, Galan, Heffernan, Jaakkola, Clancy, Hay, Fisher, Hutchinson.
Hearts (from): Kello, Hamill, Grainger, Jonsson, Webster, Elliott, Driver, Templeton, Obua, Sutton, Stevenson, McGowan, Novikovas, Skacel, Smith, Zaliukas, Robinson, MacDonald, Mrowiec.
