Swansea City midfielder Kemy Agustien is out for at least three weeks due to an ankle injury, but Brendan Rodgers hopes goalkeeper Michel Vorm will be fit to face Wigan Athletic.
Agustien suffered the ankle injury in training prior to the recent home defeat by Norwich City and he has undergone a small operation on the problem.
The Dutchman has made 15 appearances so far this term, having also been troubled by hamstring problems earlier in the campaign.
But he has found himself largely limited to bench duty, initially by the form of Mark Gower and more recently by the loan signing of Gylfi Sigurdsson.
Swans boss Rodgers said in the Evening Post: "Kemy had a scan which showed he needed a small operation.
"Hopefully the operation he has had will ensure that in the next three to five weeks, he can come back into the squad with no problem."
Meanwhile, Rodgers is optimistic that Vorm will shake off the virus which ruled him out of Swansea's defeat at Stoke last weekend.
Vorm has also been forced to skip the Netherlands' friendly with England on Wednesday and Rodgers is expecting the keeper to return to training in time to be available for the weekend's game at Wigan.
He added: "Michel has stayed with us because he's had a virus that a few of the players have had.
"He was being sick and everything else, but he has come around well and we hope he will be back in training with us on Wednesday.
"We think he should be fine for the weekend."
