MLS released the names of available players yesterday afternoon after each team was given the opportunity to protect 11 players. The Union have until 1 p.m. tomorrow to select no more than one player from 10 of the 15 teams by faxing a list to MLS headquarters in New York.

Union coach and general manager Peter Nowak and his top assistant, John Hackworth, were assistant coaches on the U.S. national team before being hired in Philadelphia. So the Philly coaches are familiar with Clark, 26, a midfielder for the Houston Dynamo, and Hejduk, 35, a defender for the Columbus Crew.

Albright, 30, and Convey, 26, who both played their high school soccer at Penn Charter, are also former U.S. national team players.

Albright is a defender on the New England Revolution, and Convey is a defender on the San Jose Earthquakes.
