Portsmouth midfielder Niko Kranjcar is out for up to three months after undergoing ankle surgery.
The Croatian ruptured ligaments in his ankle while playing for his country in a friendly against Slovenia last week.
He missed Pompey's 1-0 defeat by Manchester United on Monday night and now faces a lengthy spell on the sidelines.
Pompey have confirmed that Kranjcar underwent an operation on Wednesday morning to repair the damage.
The FA Cup winners have also admitted that the former Hajduk Split ace will be absent for between eight and 12 weeks.
Kranjcar's injury could prompt Harry Redknapp to move into the transfer market after the Portsmouth boss revealed earlier in the week that he is considering loan deals.
Redknapp started with new signing Armand Traore on the left of midfield against United before fellow new boy Jerome Thomas came on as a substitute in the second half.
