Frans, Safranko and Sow unavailable. Pawlett available. No further squad news.
United were denied the chance to close the gap at the top as their fixture at Dunfermline was postponed. Previously United lost 2-1 at lowly Partick Thistle in a serious blow to their title hopes.
Just as United seemed to be building momentum again they lost at Partick. United may be more competitive these days, but they are not scoring enough goals. They have only scored more than once in one of their last nine fixtures.
Freddy Frans is unavailable along with Osman Sow. Pavol Safranko has been called up on international duty with Slovakia and will also miss the forthcoming Alloa fixture.
Peter Pawlett is available after suspension and should be straight back in the starting XI.
United are undefeated in their last five matches at home (4W 1D).
