Arsenal midfielder Jack Wilshere has been ruled out of action for three months after undergoing surgery on his ankle.
The England international limped off the field during the Gunners' 2-1 defeat at the hands of Manchester United last weekend following a challenge by Paddy McNair.
Arsene Wenger revealed in the immediate aftermath of the Premier League clash last weekend that Wilshere would be "out for a while", and the club has this afternoon confirmed that the 22-year-old is not likely to return until the end of February.
A statement on the North London outfit's official website read: "Jack will be out for approximately three months. An assessment with a specialist confirmed the need for an operation and the 22-year-old had successful surgery to his ankle in London on Thursday afternoon.
"Jack will now commence his injury rehabilitation programme with the Arsenal medical team. Everyone at the club wishes Jack a speedy recovery and look forward to seeing him back on the pitch as soon as possible."
Wilshere has made 22 appearances for club and country so far this season.
