AFC Bournemouth will be without Callum Wilson for a minimum of six months after scans confirmed the striker has suffered a ruptured anterior cruciate ligament.

Wilson sustained the injury to his right knee during Sunday's (AEST) 2-1 defeat at Stoke City and will undergo an operation next week.

The 23 year-old had enjoyed a flying start to his debut Premier League season, scoring five times in seven matches – including a hat trick when Bournemouth secured its maiden top-flight win 4-3 at West Ham United.

"It's very disappointing for Callum, after what has been an exceptional start to the season, but I am sure he will come back fitter and stronger," Bournemouth manager Eddie Howe told the club's official website.

"Callum is the type of character who won't be fazed by such a setback, and I am sure he will turn this experience into a positive in the long run.

"As I have said many times before though, this kind of setback offers others the opportunity to step up to the plate, show everybody what they can do and make a real impact at this level."
