Arsenal Confirms Unwelcome Diagnosis: Key Player Out Before Season Start

The 25-year-old defender played through injury during France's World Cup semi-final run, and while he won't require surgery, he faces an extended period on the sidelines.

“Further specialist consultations upon William’s return to London have confirmed that he has sustained a back injury, which will require a period of rehabilitation.

Extensive assessments have concluded that surgery is not advisable, and William’s rehabilitation programme will start immediately with the aim of him being back in action as soon as possible. He is expected to be out for an extended period,” the club stated in an official announcement.
