Simone Biles has withdrawn from the final of the individual all-around gymnastics competition at the Olympics due to concerns over her mental health, USA Gymnastics confirmed on Wednesday. 

"After further medical evaluation, Simone Biles has withdrawn from the final individual all-around competition at the Tokyo Olympic Games in order to focus on her mental health," USA Gymnastics said in a statement. 

The U.S. federation said a decision on whether Biles would compete in the individual event finals would be made following the daily evaluation.
