Ipswich winger Luciano Civelli is not expected to play again this year after undergoing reconstructive knee surgery.
The 22-year-old Argentine suffered ligament damage to his right knee in the 1-1 draw with Burnley on March 17 and went under the knife in London on Friday.
Club physio Matt Byard told Town's official website: "Luca ruptured his anterior cruciate ligaments and also had extensive damage to his lateral collateral ligaments and tore cartilage as well."
He added: "It's obviously a long-term injury and we are not expecting him to return to training until the new year.
"He will need time after that to build up his match fitness but the knee, post surgery, is strong and stable and we anticipate Luca completing a full recovery."
