"After further medical evaluation, Simone Biles has withdrawn from the final individual all-around competition at the Tokyo Olympic Games, in order to focus on her mental health. We wholeheartedly support Simone’s decision and applaud her bravery in prioritizing her well-being," USA Gymnastics wrote on Twitter.
The athlete will be further evaluated to determine whether she should take part in next week’s final competitions.
On Tuesday, Biles withdrew from the women's team gymnastics final at the Olympics.
Biles is the most decorated US women's gymnast ever with 31 World Championship and Olympic medals.
