Leicester City striker David Nugent will be out "for four or five weeks", according to Foxes boss Sven-Goran Eriksson.
The former Portsmouth striker picked up a hamstring problem during last weekend's win against Southampton.
"It's disappointing but it looks like he will be out for four or five weeks," Eriksson told reporters. "It is not good news."
The Swede increased his attacking options on Wednesday night with the signing of Jermaine Beckford from Everton.
