Manchester City full-back Benjamin Mendy has undergone surgery on the cartilage in his left knee.
Mendy missed seven months of City's Premier League title-winning campaign last term after rupturing the anterior cruciate ligament in his right knee.
No timescale has been given on the 24-year-old's return to action.
Mendy was due to link up with the France international squad this week but withdrew and underwent the procedure in Barcelona.
