Spain are adamant that Andres Iniesta was only substituted as a "precaution" after he sustained a thigh injury in Tuesday's 6-0 hammering of Poland.
Iniesta was influential in both of Spain's opening goals in Murcia but after 39 minutes the Barcelona midfielder walked over to the bench and asked to be substituted.
He appeared to feel a tweak in his thigh, a potentially worrying development for a player who was restricted to 20 Primera Liga starts last season due to a succession of thigh problems.
However, Spanish football federation sporting director Fernando Hierro has sought to play down suggestions that Iniesta could become the latest high-profile injury victim prior to the World Cup finals.
"It was as a precaution more than anything else," Hierro said. "He has a slight strain. He's fine, it isn't a problem."
