The group is comprised entirely of domestic-based players and will form the core of players for the friendly against El Salvador on Feb. 24 at Raymond James Stadium in Tampa (TV: ESPN Classic, TeleFutura, live, 7 p.m. ET).
"These are important opportunities for these players as we continue to formulate our plans for the roster for the World Cup," said Bradley. "This camp and the game against El Salvador provide a chance for the coaching staff to get one more long look at this group. El Salvador demonstrated during World Cup qualifying that they are a difficult team to beat, so we expect a good match."
Brian Ching and recent Philadelphia Union signee Michael Orozco are the only players who were not in the January camp that preceded the game against Honduras.
