Leeds striker Tore Andre Flo faces a spell on the sidelines with a broken foot.
Flo broke his foot in training last week and he missed Tuesday's victory at Hull with the problem.
The former Chelsea and Rangers man is expected to be out of action for six weeks and Leeds boss Dennis Wise admitted it was a major blow to lose the Norwegian international.
"He (Flo) has a hairline fracture and is going to be out for six to eight weeks, which is a massive blow," said Wise.
"It's not nice but sometimes that's the way it goes."
Leeds are also sweating over the fitness of David Healy after he picked up an arm injury against Hull.
The Northern Ireland international is expected to undergo scans on the problem to find out the full extent of the injury.
