Locke back from knock for Killie
He missed the 2-1 defeat to Aberdeen on Saturday with an ankle knock but has recovered in time to feature against Well.
Otherwise, Killie boss Jim Jefferies expects to name a similar squad to the one who faced the Dons.
Killie (from): Smith, Greer, Hay, Lilley, Koudou, Wright, Fowler, Sylla, Quinn, Gibson, Leven, Wales, Nish, Naismith, Harpur, Ford, Di Giacomo, Locke.
