Valdes tore his anterior cruciate ligament in Barcelona’s 3-0 win over Celta Vigo and faces six months on the sidelines, ruling the 32-year-old out of the World Cup.
Del Bosque spoke with Spanish radio station Onda Cero and revealed his first thought was sympathy for Valdes.
“It’s very sad. It’s a very bad injury for him,” the former Real Madrid coach said. “It’s always bad when you can’t play for your club or at the World Cup.
“I don’t want to get into who might be Victor’s substitute. The first thing is to hope he recovers well. At the moment we’ve not thought about anything else.
“He is our only thought as he is in a bad situation.”
In addition to Valdes, Napoli's on-loan Liverpool keeper Pepe Reina and out-of-favour Real Madrid star Iker Casillas were in Spain's last squad, for the friendly match against Italy earlier in March.
Manchester United's David De Gea and Real Madrid's Diego Lopez - who has replaced Casillas as number one choice for club if not country - are expected to compete for the remaining slot, unless Del Bosque makes the unlikely call to drop Casillas.
Barcelona took to Twitter to express their sympathy with the stricken keeper, whose contract expires this summer.
