On-loan goalkeeper Graham Stack is unlikely to make another appearance for Wolves following knee surgery.
The 26-year-old Reading keeper is on loan at Molineux until January, but will miss the next four weeks after undergoing surgery to repair a damaged cartilage.
Stack's injury means manager Mick McCarthy has just Carl Ikeme as back-up to regular number one Wayne Hennessey.
"We expect Stacky to be out four to six weeks, although he thinks he'll be quicker than that," McCarthy told the club's official website.
"Carl has been chomping at the bit to get back. He is a player with a lot of ability so it's good to have him back."
Meanwhile, Wolves have been boosted by the news that veteran defenders Jody Craddock and Gary Breen are both close to first-team returns following recent injuries.
