Jack Wilshere has sustained a hairline fracture to the navicular bone in his left foot.
Wilshere suffered the injury during England's international match with Denmark on Wednesday night at Wembley Stadium, in which he played 59 minutes.
Following initial scans carried out by the FA on Wednesday night, further investigation by Arsenal's medical team has discovered a crack to a small bone in Jack's left foot - the navicular, an area of his foot which has not been previously injured.
Jack will require a period of approximately six weeks' rehabilitation, before starting to regain his match fitness.
