The French forward was stretchered off the Molineux field 10 minutes from the end of the Midlands derby with a twisted knee although manager Steve Bruce has revealed that it is not the same problem that forced Dugarry to have a knee operation in August.
"We will know more in the next 24 hours but we don't think it is too serious," Blues boss Steve Bruce said.
"The knee is twisted but this is a totally separate thing to the problem he had with his knee recently."
