Wolves have suffered a massive blow in their bid to avoid the drop with Jamie O'Hara ruled out for six to eight weeks after undergoing groin surgery.
The influential midfielder has been missing from the club's line-up since featuring against Blackburn over three weeks ago due to a groin injury.
The Premier League strugglers had hoped to keep the ex-Tottenham man available as long as possible in an attempt to stay up, however, the move has ultimately failed to bear fruit.
The club's long-serving defender Jody Craddock is also facing an extended spell on the sidelines after an operation on a hamstring problem.
The former Sunderland stopper has not made an appearance since December and the 36-year-old is now expected to be sidelined for up to five weeks.
"Both Jamie and Jody have undergone successful operations," head of Wolves' medical department Steve Kemp told the club's official website.
"Jamie has been struggling with a groin problem for several months and every attempt had been made to maintain his availability whilst trying to strengthen and rehabilitate the groin at the same time.
"Unfortunately this was not possible and it is hoped that surgery should rectify the problem although means he will be out for a further six to eight weeks.
"Jody has also undergone a minor procedure on a persistent hamstring problem and, while it is always difficult to predict, he is hoping to be available again within five weeks if his rehabilitation progresses well."
