Wolves winger Chiquinho is facing a long spell on the sidelines after sustaining an anterior cruciate ligament injury during a pre-season friendly.
The Portugal Under-21 international made a positive impression after arriving at Wolves from Estoril in the January transfer window.
He made nine appearances in all competitions for Wolves in the final three months of the 2021-22 season and assisted three goals in six Premier League outings.
Chiquinho had been expected to play a prominent role under Bruno Lage this coming season, but he may now miss the remainder of the year.
Wolves announced on Sunday that the 22-year-old suffered the injury during a collision with a Burnley player in a behind-closed-doors friendly the previous day.
Scans confirmed an injury to the ACL and Chiquinho will now undergo surgery before beginning a period of rehabilitation.
Wolves, who finished 10th in the Premier League last season, begin their 2022-23 campaign with a trip to Leeds United on August 6.
