Mark Geiger, 2012 Examiner.com Referee of the Year, is one of 25 names on the final list of referees, and will join three other PRO officials for the Brazil 2014 World Cup.
Geiger refereed 13 games in Major League Soccer in 2013 -- including two crucial playoff games last season -- and is widely viewed as the top American referee.
Mark Hurd (U.S.) and Joe Fletcher (Canada) will join Geiger as assistants this summer, alongside their support duo of Eric Borja (U.S.) and Roberto Moreno-Salazar (Mexico).
"This is fantastic news for our referees," said PRO's Peter Walton in a statement. "This reflects the very high standard of officiating we have within our ranks."
They are one of 25 referee crews and eight support groups from 43 countries selected by the FIFA Referee Committee for the tournament. They are one of just six groups combining multiple nationalities.
Geiger was the 2011 MLS Referee of the Year, referee one game at the 2013 FIFA Club World Cup, the group stage at the 2012 London Summer Olympics and the final of the FIFA U-20 World Cup in Colombia in 2011.
It's the first selection of an American since Brian Hall refereed two games at the 2002 Korea/Japan World Cup.
