Coventry City manager Aidy Boothroyd has said defender James McPake will be out of action for between four to six weeks.
McPake limped of at Oakwell on Monday in the 11th minute of the defeat at Barnsley and was replaced by Martin Cranie.
Boothroyd did not reveal the type or extent of the injury, but it will come as a blow as Ben Turner is still two weeks away from retuning from a knee injury which has kept him sidelined since November.
