The matches in Mexico are qualifiers for the 2013 U-20 World Cup, and if the U.S. qualifies, Gil could miss even more time. The World Cup starts June 21, 2013, in Turkey. The Cup final is set for July 13.
Gil, a likely starter in RSL's midfield in 2013, was called up three times last season, but competed only once, joining the U-20s for the Marbella Cup in Spain in October.
