Swindon will be without Alan Sheehan for the visit of Leeds.
The full-back is unavailable due to the terms of his loan agreement and is still with his parent club receiving treatment on a hamstring problem in any case, so Lescinel Jean-Francois is likely to continue at left-back.
Vincent Pericard is hopeful of returning from the minor hamstring strain that kept him out of last week's win at Stockport.
Simon Ferry, who was set to play the final game of his loan spell against United, has extended his loan until the end of the season but fellow loanee Ben Hutchinson misses out after returning to parent club Celtic.
Alan O'Brien (hamstring) could return to training on Thursday, while fellow midfielder Kurt Hammonds (knee) is set to undergo surgery in the near future.
Defender Callum Kennedy is continuing his recovery from a pelvic stress fracture and is three weeks away from a return to training.
Leeds manager Simon Grayson is expected to add new signing Max Gradel to his squad for the return to league action.
The 22-year-old completed his permanent move to Elland Road in time to be included.
Grayson, not expected to make many changes to his starting line-up, started with Argentinian striker Luciano Becchio on the substitutes' bench in Saturday's FA Cup draw at Tottenham and played Robert Snodgrass in an advanced role just behind Jermaine Beckford.
The Leeds boss must decide whether to retain the same formation, or switch things around slightly, with one eye on his side's game with Colchester at Elland Road on Saturday.
Leeds are chasing their first league win since the 4-2 success at Stockport at the end of December having drawn against Wycombe and losing at Exeter in their last two matches.
