Claudio Reyna, who played 112 games for the U.S. national team, has called a press conference for Wednesday to announce that he is retiring midway through his second injury-plagued season with MLS's New York Red Bulls.
The 34-year-old Reyna, who was known as Captain America, spent 13 years in Europe at clubs in Germany, Scotland and England before joining New York in 2007 as its first Designated Player.
He started just six MLS games this season and has not played since May 25 because of back problems.
Reyna, whose history of injuries late in his European career made him a risky acquisition, played 21 games in 2007. A toe sprain sidelined him late in the regular season.
The Red Bulls are not expected to get any salary cap relief for the $325,000 portion of Reyna's salary that counted against the cap, but they are in the the midst of shuffling their roster for the second half of the 2008 season.
