Fulham boss Roy Hodgson has revealed that midfielder Kagisho Dikgacoi will be absent for six weeks with ankle ligament damage.
The South Africa international limped out of Saturday's goalless draw with Bolton Wanderers and scans have confirmed a ligament problem.
Andrew Johnson, Paul Konchesky, Clint Dempsey and John Pantsil are also still sidelined, but midfielder Simon Davies and striker Bobby Zamora could return for Tuesday night's visit of Burnley to Craven Cottage.
"Bobby is fine and has recovered from his sickness and will be back in contention, as is Simon Davies," confirmed Hodgson.
"The game at Bolton was once again an expensive game for us because we got a point but have lost another player as Dikgacoi will be out for five to six weeks."
Dikgacoi has made 10 appearances for the Cottagers this season.
