Swansea City will wait to find out more about the knee injury sustained by Chico Flores on Thursday night.
The Spanish centre-back limped out of the Europa League loss to St Gallen in the second half but manager Michael Laudrup said it was too early to detect the extent of the issue.
"I talked to the doctor and we have to wait a couple of days to know. It was a knock to his knee, but we can't say any more about how long he will be out," he said.
"He was already suspended for Norwich on Sunday, but we will have to wait a couple of days to know how bad it is."
