CARSON, Calif. -- John O'Brien signed with Chivas USA on Tuesday and was selected to play in the U.S. national team's upcoming exhibition game against Jamaica.
The 28-year-old midfielder played 84 games during his six years with Dutch powerhouse Ajax Amsterdam, but was sidelined most of the last two seasons because of recurring injuries to his Achilles tendon and hamstring.
He left Ajax Amsterdam last February to join ADO Den Haag, a much smaller club.
"I'm happy to be back home in Los Angeles," the Marina Del Rey native said at a news conference Tuesday. "To Chivas USA's fans, I want to say that I promise to give 100 percent to help the team win this year."
O'Brien could make his MLS debut Saturday when Chivas USA plays D.C. United at RFK Stadium, according to team spokesman Keegan Pierce.
O'Brien was also chosen to play for the U.S. in next Tuesday's exhibition game against Jamaica in Cary, N.C. The match will be the last for the U.S. squad before coach Bruce Arena announces his preliminary roster for this summer's World Cup in Germany.
O'Brien was one of three Americans to play every minute of the 2002 World Cup, when the U.S. team reached the quarterfinals. He scored a goal in the fourth minute of the Americans' opening upset of Portugal, and set up the lone U.S. goal in a 1-1 tie with South Korea.
