Wolves have been forced to postpone Steven Mouyokolo's comeback after he suffered a minor injury setback.
Mouyokolo has played just four league games since joining Wolves from Hull in June 2010 and a season-long loan spell at FC Sochaux was cut short after he suffered a cruciate ligament injury.
He is nearing full fitness following a long spell on the sidelines, but a small unrelated problem has prevented the defender from making a return to first-team action.
"Mouyokolo had a small setback with another injury which is 100 per cent expected when you come back from a long time out and have trained hard to take the next step," Stale Solbakken told the Express and Star.
"It's just a minor thing. He trained with the reserves for a week or so before the small setback but I don't think it's too serious.
"He's been out for so long that he'll need quite a few weeks to get back."
Midfielder Jamie O'Hara is halfway through his rehabilitation from a hernia operation, while goalkeeper Wayne Hennessey is nearly ready to push for a place after a knee injury.
"Wayne is out there training now and that's going to plan," said Solbakken.
"It isn't about playing a match for him yet - he needs to get into small-sided games in training before he can do that."
