Hernandez will miss Melbourne Victory's round five match against Newcastle Jets at Etihad Stadium on Thursday September 3 in preparation for Costa Rica's fixtures against Mexico in San Jose on September 5 and El Salvador in San Salvador on September 9.

Costa Rica are on track to make their third consecutive World Cup appearance, leading the final stage of CONCACAF qualifying with 12 points from six matches, two ahead of closest rivals USA and Honduras.

The top three teams from the CONCACAF group of six will progress directly to next year's tournament in South Africa, with the fourth-placed team to face the fifth-best team from South America for another berth.

Hernandez, who netted two stunning goals in Melbourne Victory's round two clash against Brisbane Roar less than two weeks ago, was part of Costa Rica's squad at the 2006 World Cup and has made three appearances in qualifiers this year.
