Spain are set to be without playmaker Andres Iniesta for their second Group H match against Honduras on Monday.
The Barcelona star limped out of their shock 1-0 defeat to Switzerland with a thigh strain after 77 minutes and will be tested on Monday before the game.
Spain head coach Vicente Del Bosque has revealed Iniesta will probably be absent for their must-win clash with Honduras.
"Everyone is ready to play except Iniesta," he said.
"He suffered an injury to his thigh, it's an injury which has nothing to do with his previous problems.
"It happened in the first match against Switzerland."
Iniesta's spot in Spain's starting XI is likely to be taken by Arsenal star Cesc Fabregas if he misses out.
