Angelo Alessio's Kilmarnock squad is almost at full fitness ahead of Saturday's Rugby Park clash with Hearts.
The only confirmed absentee is Scotland centre-back Stuart Findlay, who has been ruled out for at least three months out with a tendon injury.
Striker Osman Sow has recovered from an ankle complaint but needs to top his fitness levels.
Hearts defender Craig Halkett has resumed training but his return has come too late for him to play this weekend.
The former Livingston centre-back has missed the last six weeks with a knee injury and remains short on fitness.
