Wolves boss Gary O'Neil has confirmed a major hamstring injury for Matheus Cunha.
Cunha broke down last week in the home defeat by Brentford.
O'Neil said: "It's obviously a big blow to us, to the team and Matheus because of the work he's been doing.
"The form he was in was exceptional.
"He's started working on it already, so we're just going to monitor it week by week, day by day, see how far he can come and how quickly we can get him back,"
