Both players picked up injuries playing for their respective clubs over the weekend, and their statuses for Friday's friendly against Guatemala in San Diego and next week's Gold Cup group games are undetermined.
Gatt injured his knee playing for Norwegian champion Molde, and U.S. Soccer is awaiting the results of an MRI before coming to a conclusion on the winger's availability. Gatt has two caps, as he started last November's friendly in Russia and came on as a substitute in the January friendly against Canada.
Ashe, who was called in by Klinsmann for the first time for the USA's friendly against Belgium in May only to miss out because of an injury suffered with the Houston Dynamo, was hurt again Saturday in a clash with New York Red Bulls Designated Player Tim Cahill. He is considered day-to-day with a thigh contusion, according to U.S. Soccer, but the left back has reported to training camp, where he will be evaluated by the national team's medical staff.
Should one or both players be ruled out from playing, Klinsmann could opt to turn to the 12 players on the 35-man provisional roster that he did not put on his final roster in as reinforcements.
