Russian gymnasts upset the U.S. Olympic team in Tokyo on Tuesday after American superstar Simone Biles withdrew from the competition.

Biles, the reigning all-around Olympic gold medalist and one of the faces of the American contingent in Japan, left the team final after a disappointing vault performance with what USA Gymnastics called "a medical issue." Biles "will be assessed daily to determine medical clearance for future competitions," the U.S. gymnastics governing body said.
