[WORLD CUP COUNTDOWN] Philadelphia is the center of the soccer world in 2010. Site of the NSCAA Convention and MLS SuperDraft, it will be the home of the MLS expansion Union, which opens at its new PPL Park in Chester, Pa., on June 27. It will also be the site of the U.S. national team's sendoff game against Turkey before heading off to the World Cup in South Africa.

The NFL Philadelphia Eagles announced Tuesday that the USA will face Turkey May 29 at Lincoln Financial Field, where they play their home games.

The Linc will be the home of the Union until PPL Park opens and is one the short list of World Cup 2018/22 venues.

A press conference to announce the game will be held Wednesday at the NovaCare Complex with Eagles president Joe Banner, Philadelphia Mayor Michael Nutter and Sunil Gulati, the president of the U.S. Soccer Federation.
