The 31-year-old goalkeeper picked up a calf injury during Spain's 1-0 defeat to South Africa last night.
"Injuries never come at a good time and it is unusual for a keeper to get a leg injury but this is the situation and we will have to deal with it," Zubizarreta told Radio Marca.
Valdes is expected to leave Camp Nou when his contract expires next summer.
