Simone Biles will compete in Tuesday's balance beam final, the last women's event on the Tokyo Olympics gymnastics schedule.
"We are so excited to confirm that you will see two US athletes in the balance beam final tomorrow - Suni Lee AND Simone Biles!! Can’t wait to watch you both!" says USA Gymnastics.
The American will compete in Tokyo for the first time since her withdrawal from the women's team final after her opening vault, citing mental health issues.
The 24-year-old American, who won four golds at the 2016 Rio Games, dropped out of the all-around, floor exercise, vault and asymmetric bars finals.
Biles is the reigning world champion on the beam and picked up an Olympic bronze on the apparatus in Rio.
Biles has suffered a crisis of confidence in Tokyo, as she dealt with the 'twisties' - where gymnasts are disoriented during their gravity-defying sequences.
"It's honestly petrifying trying to do a skill, but not having your mind & body in sync," Biles explained on Instagram, where she answered fan questions and shared practice videos.
While some difficult acrobatic skills have to be performed on the beam, fast-paced tumbling and aerial twisting manoeuvres are limited on the apparatus, providing Biles with the opportunity to add to the team silver medal she picked up last week.
Despite not competing, Biles has been a constant presence at the Ariake Gymnastics Centre over the past week to support her US teammates. Biles cheered on Sunisa Lee, who succeeded her as Olympic all-around champion, and Mykayla Skinner, who stepped in for her in women's vault final and won silver.
