Wolves winger Michael Kightly is likely to need an ankle operation that will see him out of action for up to eight weeks.
The 23-year-old suffered the injury in Sunday's 1-0 home defeat to Birmingham and scans have indicated he will need to go under the knife.
"He's had a scan and it looks like he'll need an operation which would be six to eight weeks out," manager Mick McCarthy told the club's official website.
The injury will come as a further blow to Kightly, who had a troubled start to the season following hip and foot surgery.
The winger has impressed at Molineux since his recovery and despite admitting his disappointment, McCarthy insists it is not as bad as it could have been.
"The way he went over and rolled his ankle apparently he's quite lucky and it could have been worse," he said.
"We've not really had Michael at his full potential yet and Sunday was the first time we'd maybe seen that and then he picks up a new injury.
"It's really disappointing for him because he wants to play and he thought he was somewhere at it.
"He was really down about it all yesterday but today he's brightened up because it looks like being six to eight weeks.
"That's almost good news in terms of what could have happened."
