Nigel Clough says it is 'relatively good news' with regards to Terry Kennedy's knee injury.
United were worried the defender could be facing a prolonged spell on the sidelines, after sustaining what appeared to be a serious knee injury in the recent draw at Crawley Town.
But as Clough revealed following Tuesday's loss against Peterborough, the prognosis now appears to be much better for the young centre-half.
The Gaffer remarked: "It is relatively good news for Terry; we are looking around four weeks, after initially fearing it could be 4-6 months.
"He doesn't have much cartilage left in his knee but he has a slight nick in the bit that remains and he just needs a couple of weeks rest before starting to build up again after that."
Elsewhere, Mark Howard is expected to up his rehabilitation next week, Clough added:
"Mark has done a bit of training, but he back remains sore. We are probably looking at getting him training again in the early part of next week with a view to him being available in 10 days or so after that."
