Simone Biles has withdrawn from the final floor competition, USA Gymnastics said on Twitter.
Biles, arguably the world's greatest gymnast, has pulled back from Olympic competition in Tokyo to focus on her mental health. The 24-year-old explained in a series of Instagram posts that she has the "twisties," a mental block in gymnastics in which competitors lose track of their positioning midair.
USA Gymnastics said yesterday that Biles would be withdrawing from two other individual disciplines, vault and uneven bars.
She will make a decision about the final event, beam, "later this week."
The women's vault and bars finals are scheduled for Sunday, the women's floor final is Monday, and the beam final is Tuesday.
