Nottingham Forest's Kelvin Wilson could be out for another six weeks after suffering a setback in his recovery from an ankle injury.
The 23-year-old defender went over on his ankle in training on Wednesday and faces a prolonged spell on the sidelines.
He has yet to feature this term after sustaining the injury in a pre-season game against former club - and city rivals - Notts County.
He resumed light training this week and it was hoped he might be able to return before the end of the month.
But his latest blow has put paid to such hopes, with boss Billy Davies telling the club's official website: "Unfortunately Kelvin went over on his ankle again and could be back to six weeks out."
