Bournemouth midfielder Dan Gosling will be out for about three months after undergoing surgery on a "hip muscle injury".
The Cherries confirmed that Gosling had the operation at the weekend having suffered the injury in training.
The 29-year-old could miss his side's opening 10 Premier League fixtures.
The former England under-21 international made 22 Premier League appearances last season and has scored 17 goals in 149 games for Bournemouth.
