Defender Jackson Ragan to miss US exhibition vs Slovenia because of knee injury

CHICAGO — Defender Jackson Ragen will miss the United States' exhibition against Slovenia on Saturday in San Antonio because of a knee injury.

The 25-year-old Seattle Sounders center back aggravated a previous knee injury and is returning to his team for evaluation and treatment, the U.S. Soccer Federation said Sunday. Ragan was among the players on track for possible national team debuts.

Twenty-three players remain in camp for the match, including 16 who have never played for the national team. The game is not on a FIFA fixture date and no Europe-based players are in camp.
