It's actually a nasal fracture (a basal fracture is a skull fracture that would have had Dempsey in the ICU, but ESPN misreported this), but yeah, I think Dempsey will be fine in a few days.
My issue with Klinsmann's roster decisions are that he brought too many role players and not enough depth. Now we need cover for Altidore, and on the bench you have Johannsson, a skilled, creative scorer, and Wondolowski, a one-dimensional poacher, rather than someone who can bring Altidore's target and hold-up skills. Johnson, Boyd, or Agudelo would have fit nicely there over Wondo.
Furthermore, bringing both Davis and Green, neither of whom can play anywhere but LM (and then starting neither of them) is completely indefensible. Davis only brings one skill - setpieces, which would be replicated by Donovan or Zusi.
Also, bringing a nicked-up Gonzalez and whatever's left of Beasley was foolish. If I were in charge, I'd have left Wondo, Davis, Beasley, Gonzo, and probably Green (though it seems like bringing him may have been required in order to get him to commit to the US) at home, and brought EJ, Donovan, Ream/Parkhurst, Goodson, and Edu (cover for Beckerman, if he's going to be starting consistently).
