Wolves boss Mick McCarthy had been hopeful of O'Hara returning to action within six weeks of the operation last month but that target has now been and gone.
O'Hara will again be absent for next Tuesday's home Barclays Premier League clash with Liverpool, with McCarthy confirming: "Jamie won't be ready for Liverpool. He's going to be another week to two weeks yet."
O'Hara played a key role in Wolves surviving in the Barclays Premier League last season when on loan from Tottenham but he has struggled to make the same impact during the current campaign before his injury setback.
