Jackie McNamara’s out-of-sorts side have failed to win in 10 games as a season that offered much promise threatens to fizzle out in tepid fashion.
United midfielder John Rankin is a doubt after getting stitches in a leg knock while Jaroslaw Fojut is also struggling for the Tannadice clash with an ankle injury but fellow defender Callum Morris could return after a thigh strain.
Hamilton’s Dougie Imrie will return to the Accies squad for the trip to Tannadice.
Imrie missed the 1-1 draw with St Johnstone last week but Martin Canning has said the midfielder will be in the reckoning this weekend as Accies look to break their own run of poor form; they have not claimed a win bonus for a dozen matches.
Defender Lucas Tagliapietra could also feature after returning to training following ankle trouble but forward Andy Ryan (groin) remains out.
Player-manager Canning also misses out through suspension after his red card against St Johnstone and Jesus Garcia Tena is likely to deputise.
