Marseille forward Andre Ayew has undergone successful shoulder surgery but will be out of action for the next three months.
The 22-year-old Ghana international went under the knife with a view to being fit for the start of the new season.
A short statement on the club's website read: "The operation on the left shoulder of Andre Ayew, conducted on Tuesday in Lyon by Dr Walsch, went smoothly. The Ghanaian's comeback is expected in about three months."
Ayew has been playing through the pain since picking up the problem at the African Nations Cup in January, but it was decided the operation must go ahead now after he dislocated his shoulder during Saturday's 2-1 Ligue 1 defeat at Bordeaux.
