Brazil-born Atletico Madrid striker Costa has battled an ongoing hamstring problem that limited him to just nine minutes in the Champions League final defeat to city rivals Real, a week after he was forced off 15 minutes into his side’s La Liga title decider with Barcelona.
Del Bosque also left strikers Jesus Navas, Alvaro Negredo and Fernando Llorente, midfielder Ander Iturraspe, and defenders Alberto Moreno and Dani Carvajal out of his squad, the six having been named in his initial 30-man list.
Defending champions Spain face Chile, the Netherlands and Australia in World Cup Group B. Their first match pits them on June 13 against the Netherlands — their opponents in their 2010 World Cup final triumph.
