Sounders Eddie Johnson and Clint Dempsey will be in uniform for the USA.
Meanwhile, as the Sounders continue training for their 7 p.m. Saturday match against the Chicago Fire, we asked Costa Rican defender Leo Gonzalez about the international match.
"I think a very good game for both teams," he said. "Difficult game. Costa Rica, the fans support a lot the national team. And for both team it’s difficult. They are in good position – USA in the first position, Costa Rica in the second position – so it’s a good, good game for Costa Rica. They need to win because they are at home. They want to get quickly the qualification for the World Cup."
His prediction: "I think it’s a tie game: 1-1 or 0-0."
