Fulham striker Bobby Zamora has undergone surgery on his broken leg after suffering the injury in Saturday's 2-1 victory over Wolves.
But ankle ligament damage was also discovered during the operation on Sunday, raising fears that Zamora could face even longer on the sidelines.
A statement on Fulham's website described the surgery as a success.
The 29-year-old Zamora, who made his England debut in August, signed a new four-year deal with Fulham on Friday.
Zamora moved to Fulham from West Ham in July 2008 and, after a difficult first season, came to the fore during the 2009-10 campaign with his 19 goals helping the London side reach the Europa League final and finish 12th in the Premier League.
