Altidore missed Saturday’s game for club team Sunderland because of a right hamstring injury. He still traveled to join the Americans in Miami, and U.S. Soccer announced Tuesday that doctors had cleared him after a full evaluation. An MRI showed the hamstring was normal.
Having Altidore would be a boost for the Americans, who have yet to win a World Cup qualifier in Costa Rica. Altidore has scored in five straight games, a U.S. record, with a total of seven goals.
After Friday’s game in Costa Rica, the U.S. returns home to face Mexico on Sept. 10 in Columbus, Ohio.
