The 34-year-old made 235 appearances in Major League Soccer and was a part of the 2006 USA World Cup squad.
The 34-year-old Philadelphia native spent 15 seasons in MLS with D.C. United, the LA Galaxy, New England Revolution, New York Red Bulls and Philadelphia Union. He represented the United States at the 2000 Olympics and the 2006 FIFA World Cup, winning 22 caps and scoring a single goal, on his debut against Jamaica.
Albright won the 1999 MLS Cup and Supporters' Shield double with D.C., repeated the feat with LA in 2002 before adding a third MLS Cup in 2005, and was part of New England's triumph in the 2008 SuperLiga. In total, he made 235 regular-season appearances in MLS, scoring 11 times. He was selected for the MLS All-Star team from 2004-06.
"I am extremely lucky to have played in MLS for the past 15 years, for five exceptional organizations," said Albright in a statement on the team's website. "The game itself has afforded me opportunities and experiences that I would not have had otherwise and I'm forever grateful.
"Most importantly, I'd like to thank my wife Leah, and my parents John and Patti for their continuous love and support. The men that I have had the good fortune of calling coaches and teammates have truly shaped my career and I'm especially honored to have been able to end it with my hometown club, Philadelphia Union."
The Union will honor Albright ahead of the team's final regular-season match, against Sporting Kansas City on Saturday.
