Fulham striker Hugo Rodallega is likely to miss up to six weeks of the season following an injury suffered in the 4-3 defeat to Leicester City last week.
Further tests have revealed that the groin injury is worse than first thought and the Colombian could now miss his side's action until near the festive period.
Cottagers manager Martin Jol confirmed the news at his press conference on Thursday afternoon.
Rodallega, who scored two goals in the game against Leicester, has scored just twice in the league for the London side.
