Barcelona's back-up goalkeeper Neto will undergo surgery after injuring his left wrist, the club announced on Monday.
Neto suffered the injury in training and is unlikely to be fit for Barca's opening La Liga game away to Athletic Bilbao on Friday.
"Goalkeeper Neto is to undergo surgery this Tuesday on a fractured scaphoid bone in his left hand sustained in training while on the US tour," a club statement read.
"Doctor Xavier Mir will perform the operation in the presence of the Club Medical Services. Afterwards, he will make a statement to explain how the surgery has gone and to offer an approximate recovery date."
