Spain manager Vicente del Bosque on Sunday put off until at least May 31 naming his full World Cup squad to monitor the fitness of key Real Madrid and Atletico Madrid players.
Del Bosque announced a list of 19 players for the friendly against Bolivia on May 31 and said he would name the final World Cup squad of 23 the day after that. He has until June 2 to finalise his 23-man squad.
Barcelona's Gerard Deulofeu won a call-up for the Bolivia match but is not on the list for next month's World Cup in Brazil.
Sunday's list left out players from the two Spanish teams in Saturday night's Champions League final in which Real Madrid beat their city rivals Atletico 4-1 in extra time.
