Barcelona's Dutch international Ibrahim Afellay will undergo surgery to repair a torn ligament in his left knee on Monday, the Spanish club said.
The 25-year-old winger, who had recently returned to fitness after picking up a hamstring injury in pre-season, picked up the injury during a training session last week.
The club did not give any indication of how long the player will be sidelined.
Afellay has played just a substitutes roles this season, appearing in games against AC Milan and Osasuna.
He was signed from PSV Eindhoven in December.
