Arsenal midfielder Jack Wilshere says he has undergone ankle surgery and expects to be sidelined until December.
The 19-year-old England international sustained the injury in June and hasn't played since it flared up again in a preseason game against the New York Red Bulls.
Wilshere wrote on Twitter on Monday: "Had my operation and all went well! I am feeling good will spend the night in hospital to monitor me but apart from that I am happy!"
On Friday, Wilshere tweeted he hoped to be back "around Christmas time."
