"Midfielder Jose Gomez was added to the roster for the tournament a day before the team left for Korea after defender Adrian Chevannes badly sprained his ankle during its international friendly against Costa Rica..." http://tinyurl.com/d399
Sort of surprised that a midfielder replaces Adrian. Adrian is a very good defender with speed, vision, and pace - I'm sure he'll be sorely missed...
Missing Adrian will definately hurt them. It already has in the 3-0 loss to Korea. His speed and strength surely would have helped out against a quicky hard working team like korea. Him getting injured will definately be a thorn in their side.
