Wilshere set for lengthy lay-off
Arsenal and England midfielder Jack Wilshere will be sidelined for a period of between four and five months following surgery to remedy a stress fracture to his right ankle.
Wilshere has not featured for the Gunners in a competitive game this season after suffering the injury in a pre-season friendly against the New York Red Bulls at the Emirates Stadium.
A statement on the club's official website on Monday evening read: "Jack Wilshere has this morning undergone ankle surgery at a central London hospital. It is envisaged that Jack's rehabilitation will take a period of four to five months."
The statement continued: "Under the care of two world-renowned surgeons, Jack has had the stress fracture of his right ankle repaired.
"The initial indications are that the surgery has been successful and Jack will now undergo a prolonged period of rehabilitation."
Wilshere had initially hoped that the problem would not require surgery but the club confirmed last week that an operation would be necessary.
Wilshere added on the official website: "I've had my operation and all went well. My ankle is little bit sore, but I'm already looking forward to working hard to get fit and playing again.
"I would also just like to say thanks for the many messages of support I have received from you - the fantastic Arsenal supporters. See you all soon at the Emirates."
The Gunners' prognosis means Wilshere may not play competitively for the club until late February.
