Wolves defender Yerson Mosquera is expected to miss the rest of the season with a serious knee injury.
The 23-year-old was carried off in the 82nd minute of Saturday's 3-1 defeat at Aston Villa after being caught by Morgan Rogers and twisting his knee.
The Colombia international has undergone scans to determine the severity of the injury and will now require an operation.
Wolves' head of high performance Phil Hayward said: "Yerson has now had all of the various assessments and scans which unfortunately confirm injuries to the medial collateral ligament (MCL) and the anterior cruciate ligament (ACL).
