Wolves striker Kevin Doyle hopes to be back before the end of the season.
Doyle suffered a knee injury in action for the Republic of Ireland on the weekend.
Wolves confirmed in a statement that "rehabilitation times can vary with this particular injury and Doyle still has a chance of featuring this season if he recovers within the eight week projected timespan".
The head of Wolves's medical department, Steve Kemp, said: "The scan has confirmed that Kevin has torn his MCL [medial collateral ligament]. We will be working with Kevin to get him back as quickly as the injury allows but the likely timespan is anywhere between four and eight weeks."
