Barcelona full-back Alejandro Balde has suffered a training-ground hamstring injury.
“Defender Alejandro Balde suffered a slight injury to his left hamstring during today’s training session,” the LaLiga club said on Wednesday.
“His availability will depend on how he progresses.”
The 21-year-old Spain international has started all three of Barcelona’s league games this season.
Barcelona return to action after the international break against Valencia on September 14 before visiting Newcastle in the Champions League four days later.
