Robbie Neilson is set to make his Dundee United debut in Saturday's SPL clash against his former club Hearts.
Neilson signed until the end of the season this week and could be joined in defence by Sean Dillon, who is fit again following a calf problem.
Danny Swanson (knee) and Scott Severin (broken leg) remain absent.
Hearts will be without Ian Black and Danny Grainger.
