Wilson, who has scored six goals in 21 appearances this term, also suffered a similar injury last campaign.

Manager Eddie Howe told the club's official website: "We are all devastated for Callum.

"What's important now is that he receives the support and love of his family and friends, team-mates and everyone associated with AFC Bournemouth.

"Callum showed incredible character and determination to come back from a similar setback last season and we know he has the same strength and will to do the same again."

Meanwhile, Bournemouth have handed winger Ryan Fraser a new three-and-a-half-year deal.

The 22-year-old joined the Cherries from Aberdeen four years ago and was part of the team which won promotion from Sky Bet League One in 2012-13.

Fraser has scored three goals in 13 league appearances this campaign after spending last term on loan at Ipswich.

Howe added: "Ryan has made huge strides in his development this season.

"He has had to be patient for a regular opportunity here and the next step was to produce performances on a consistent basis. We are seeing that from him now.

"Ryan deserves all the accolades he has received and hopefully there are many more to come. I see a really bright future for him."
