Chivas USA defender Jimmy Conrad is retiring after a concussion limited him to two games this season.
Chivas USA called a news conference for Thursday to announce the retirement of Conrad, a five-time All-Star over 13 seasons and 290 games in MLS, including eight years with Kansas City.
Conrad scored his 20th MLS goal in his Chivas USA debut, but hasn't played for the Goats since getting hurt in the second game of the season.
He was named MLS' best defender in 2005, and made four appearances in the league's Best XI between 2004-08. He won an MLS title in 2001 during his first four seasons in San Jose.
Conrad also has played sparingly for the U.S. national team, including an appearance at the 2006 World Cup.
