Leicester City centre-back Sean St Ledger has been ruled out of Saturday's trip to Ipswich Town through injury.
St Ledger picked up the injury during the Republic of Ireland's 0-0 draw away to Poland and manager Nigel Pearson admitted that he is unsure of when he will return.
"We've got one or two problems in the sense that Sean is injured, which is disappointing," Pearson told the club's official website.
"He's been away with his national side and unfortunately has picked up an injury. That sets him back, but I can't give a time scale at the moment."
Leicester are currently second in the Championship.
