Wolves have announced that Jamie O'Hara has been forced under the knife again in his efforts to shake off a niggling groin problem.
The midfielder has been out of competitive action since March, with a complex complaint continuing to cause him trouble.
O'Hara underwent a double hernia operation prior to Christmas 2011 and had hoped to have got to the bottom of the issue.
He is, however, back on the treatment table and has been forced to watch on as Wolves have slipped out of the Premier League and opened their quest to secure promotion out of the Championship.
A pre-season friendly outing against Walsall in July suggested he was on the road to recovery, but medical staff have advised the 25-year-old that further surgery is the best way forward.
"Jamie has been struggling to get back to full fitness since his previous surgery and there are some complex issues surrounding the groin area which are still causing problems," first-team physio Phil Hayward told Wolves' official website.
"While the initial surgery was effective in combating part of the problem, he is still suffering with various symptoms.
"It has therefore been decided to go back to a different surgeon and undergo a further operation to resolve the issues.
"It is a minor operation and should alleviate the symptoms in order to help Jamie progress towards full fitness but we won't be putting a timescale on his recovery at this moment in time."
