Arsenal will not see Wilshire until 2012
The Sun says the England midfielder, 19, will have an ankle op on Monday and has been warned he will not play until the New Year.
Wilshere has been wearing a protective boot due to the injury which has been troubling him for over a year. He broke down with the problem in the Emirates Cup and has yet to play this term.
A Gunners spokesman said: "We have given Jack time to heal naturally which is important wherever possible with a young player. The latest scans show surgery is needed.
"Everyone at the club wishes Jack a speedy recovery."
