Jack Wilshere injury: Arsenal midfielder ruled out for THREE MONTHS after undergoing ankle surgery today

England midfielder suffered the injury in 2-2 draw with United

Arsenal midfielder Jack Wilshere has been ruled out for three months after undergoing ankle surgery.

Wilshere suffered the injury after competing for the ball with Paddy McNair in the Gunners' 2-1 defeat by Manchester United last Saturday.

The England midfielder had surgery on the ankle in London this afternoon.

Wilshere posted a picture of himself after surgery on his Instagram account today, with the caption: "Ankle needed surgery in the end, went well thanks to the main man James Calder! Work hard for what you want because it won't come to you without a fight. You have to be strong and courageous and know that you can do anything you put your mind to. If somebody puts you down or criticizes you, just keep on believing in yourself and turn it into something positive."

Wilshere's career has been plagued by injuries, mainly to his ankles, and he has played fewer than 100 league games since making his debut in 2008.

He missed the entire 2011-12 campaign after suffering a stress fracture to his ankle which ruled him out for 17 months.

It was another blow for Arsenal manager Arsene Wenger who has been badly hampered by injuries during a poor start to the season in which Arsenal have slipped to eighth in the table.

Midfielder Mikel Arteta sustained a calf injury in Wednesday's Champions League win over Borussia Dortmund, joining Wilshere, Mesut Ozil, Mathieu Debuchy and Theo Walcott on the sidelines.

The victory over Dortmund did book Arsenal's place in the knockout stages of Europe's premier club competition but Wenger will be desperate to climb the league standings, starting with a trip to West Bromwich Albion on Saturday.
