WASHINGTON (AP) -
Blake Griffin has officially withdrawn from the Olympics and Anthony Davis has been added to the U.S. basketball team's roster.
Griffin needs surgery to repair torn cartilage in his left knee and joins a lengthy list of American stars sidelined this summer.
Davis replaced him in the Americans' 113-59 exhibition victory over the Dominican Republic on Thursday in Las Vegas, scoring nine points in the fourth quarter. The NBA's No.1 overall draft pick had been an alternate after failing to make the 12-playter roster for London.
