Reigning champion Spain and five other nations playing in the World Cup have booked training matches at US venues in a "Road to Brazil" series announced Friday.

Promoters Soccer United Marketing have scheduled seven matches across American venues, capping the series with Spain's June 7 match against El Salvador at FedEx Field -- the 90,000-seat home of the NFL Washington Redskins.

Other Brazil-bound teams that will make US stopovers for tuneup friendlies include African Cup of Nations winner Nigeria, Greece, Bosnia and Herzegovina, Ivory Coast and Honduras.

The schedule opens May 29 when Honduras and Turkey meet at RFK Stadium in Washington while Ivory Coast meets Bosnia and Herzegovina the next day at a venue to be determined.

Honduras will meet Israel on June 1 at Houston, Texas, while Nigeria and Greece play June 3 at the suburban Philadelphia home pitch of Major League Soccer's Philadelphia Union.

Ivory Coast and El Salvador meet on June 4 at the home park of MLS side FC Dallas and Greece will face Bolivia on June 6 at the home of the MLS New York Red Bulls in Harrison, New Jersey.

While not part of the series, England's pre-World Cup schedule also features a US stopover for matches at Miami against Ecuador on June 4 and against Honduras three days later.

Portugal, featuring Cristiano Ronaldo, will also play US friendlies ahead of going to Brazil, facing fellow World Cup qualifier Mexico on June 6 at Foxboro, Massachusetts, and the Irish four days later at East Rutherford, New Jersey.
