Landon Donovan's ankle and Jermaine Jones' knee got both sent home early from camp.
“Landon is still struggling with the ankle injury from a couple weeks ago, so he will go back to Los Angeles and try to get back to 100 percent,” Jurgen Klinsmann said in a U.S. Soccer release. “Jermaine’s case is more of a concern. His knee was bothering him all night but he battled through."
Matt Besler and Tim Howard also left the side to give their backups some playing time. Klinsmann tipped Clarence Goodson and Brad Guzan, respectively, to start in their places in Tuesday night's 9:30 qualifying finale against Panama at Estadio Rommel Fernandez.
Injuries were not cited for either Besler's or Howard's release.
Panama must beat the U.S., have Mexico lose at Costa Rica and make up three goals of differential to beat out Mexico for fourth place and the playoff spot against New Zealand.
