Fulham midfielder Damien Duff is likely to be out for the rest of the season with a knee injury.
The 35-year-old has been struggling with the problem for a number of weeks and may require surgery.
He has not featured since the Whites were knocked out of the FA Cup by Sheffield United on 4 February.
Manager Felix Magath said: "Damien's injury is worse. We have to expect that he will not play any more this season.
"The problem is his knee - an injury from three weeks ago which he had before I arrived here - and maybe he needs an operation."
