Balde featured in Spain's win, but was substituted at half-time and eventually released back to Barça this morning.
However, after scans on Friday, Barça announced Balde has avoided a serious setback.
"The tests carried out this morning have confirmed that he suffers from discomfort in the adductors. It is low and its evolution will mark his availability," the club declared in a statement.
It means Balde appears set to be available for El Clásico against Real Madrid later this month.
