Michael Parkhurst has been added to the United States roster ahead of two World Cup qualifiers later this month.
The defender was brought in from Germany to prepare for Friday night's game at Costa Rica after Brad Evans was hurt playing for the Seattle Sounders on Saturday night.
Parkhurst, who plays for Augsburg in the Bundesliga, started in five of six matches in the Americans' 2013 CONCACAF Gold Cup championship, including the final.
The Americans resume their qualifying campaign Sept. 6 in Costa Rica, then return home four days later for a game against archrival Mexico in Columbus, Ohio. They currently top the qualifying group from the North and Central American and Caribbean region.
"The Costa Rica game in San Jose is the biggest game in 2013 for all of us because we want to win there," said Klinsmann in a statement. "We want to qualify as soon as possible for the World Cup in Brazil. We want to get the first ever three points in World Cup qualifying in Costa Rica.
"Everyone needs to understand there will be a lot of tension. We need to be very well prepared mentally and physically and give them a real game. And if you look at the quality of our roster and our players, we have the quality to get the three points."
