Neto has suffered a fractured wrist, leaving him out of action for up to eight weeks.
According to beIN sports network, the fracture is in the left wrist.
The Brazilian was only signed this June from Valencia, for 26 million Euros.
This followed the departure of Jasper Cillessen, in the opposite direction.
The injury was suffered before the game against Napoli this past weekend.
He is expected to undergo surgery today.
His injury will leave defending La Liga champions Barcelona, without an experienced senior backup keeper for current first-team number one Marc-Andre ter Stegen.
This will be a concern for Ernesto Valverde ahead of Friday’s season opener against Athletic Bilbao.
Barcelona does have its Barcelona B team to call on if needs must.
The likelihood is that Valverde will call up 20-year-old Inaki Pena. He was granted the privilege of traveling with the first team on their mini-tour of the USA.
Neto is not expected to be in contention for a return to play until October at the earliest.
With the Spanish transfer window open until September 2nd, the Catalonians do have the option of signing another backup keeper if they must.
We have already seen Liverpool do so after a freak injury to their number one Alisson Becker. Manchester City aired on the side of caution and brought in Scott Carsona t the last minute as back up too.
Both those clubs signed their backups on free transfers. This may be a route Barca go down. They are currently counting Euro’s to see if they can muster up the cash to buy Neymar.
