Villa escapes sanctions over slap
"The disciplinary committee examined the incident and found no grounds to open a case," a spokesman said during Wednesday's media briefing. "A case was never actually opened."
Villa, who scored both Spain's goals against Honduras in Monday's Group H game, aimed a slap at Izaguirre late in the first half.
Villa admitted after the game that he would need to better control his temper in future.
"It's not something that I am proud of," Villa said in an interview with Spanish broadcaster Canal Plus.
"They're just instincts... in this case I wasn't expecting him to tread on me," he added.
"I was merely standing there and the reaction was to stick my arm out. I'll try in future to keep my cool."
