CHESTER, Pa. -- U.S. coach Jurgen Klinsmann offered no guarantee that World Cup hero goalkeeper Tim Howard will return to the national team in September.

Howard hasn't played for the American squad in more than a year, since his famous performance in the Americans' 2-1 loss to Belgium in the round of 16 last summer in Brazil.

After the tournament, Howard announced that he -- with Klinsmann's blessing -- would take a one-year hiatus from international play to spend more time his children.
