West Ham have revealed that Jack Wilshere has undergone surgery on his ankle.
It was learned that the midfielder will miss up to six weeks with the injury.
The 26-year-old, who joined the Hammers after leaving Arsenal at the end of his contract in the summer, was ruled out with the problem prior to Sunday’s 3-1 win at Everton.
Wilshere will now miss key fixtures against Chelsea, Manchester United and Tottenham as West Ham attempt to climb the Premier League table following a slow start to the new season.
West Ham head of medical Richard Collinge has confirmed the operation went as planned.
“Jack underwent successful surgery in London on Monday morning for a minor ongoing ankle issue.
“The surgeon was happy with the procedure and all went as planned.
“We envisage he will only need a relatively short period of rest and will then start his rehabilitation. Jack is focused and determined to get back training and playing as soon as possible,” he said in a statement on the club’s official website.
