Simone Biles is too make one last bid for Olympic glory on Tuesday evening.
She has decided to compete on the beam at the gymnastics after a troubled week.
USA Gymnastics confirmed that she will join Tokyo gold medalist Sunisa Lee in the balance beam competition.
A statement said: ‘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!’
The six times medalist is likely to make Tuesday's attempt at gold her last appearance at the Olympic games following a troubled week in which she has told officials she is suffering from poor mental health, leading her to drop out of five competitions.
The troubled athlete donned a black safety face mask as she took a third row seat above the gymnasium floor on the day she revealed she had withdrawn from another event, the floor exercise, for which she is the current champion
Simone has stressed that being aged 24 and the oldest member of the US women’s team has added two her anxieties and is one of the reasons ’the demons’ have affected her inTokyo.
Simone, one of the greatest all time Olympic gymnasts will be 27 when the next games are staged in Paris in 2024.
She said she had lost confidence and worried about competing and was suffering the ’twists’ which hamper the ability to leap and jump through the air.
USA Gymnastics said on Sunday that Biles had withdrawn from Monday's floor exercise final, which was one of the four golds Biles won in Rio in 2016, and would make a decision about her last scheduled final on the beam later this week.
Biles had been expected to improve on her Rio Games gold haul after qualifying for all five individual finals in Tokyo but pulled out of the all-around, vault, asymmetric bars and floor exercise medal events in order to protect her mental health.
Biles shocked the world when she withdrew from the team final last week after a single vault, citing mental health issues.

Asked how Biles was doing, team-mate Mytkala Skinner Skinner told reporters she was "handling it better than I thought".
"Every day she's been laughing and giggling, super supportive, and I'm sure when she gets home it'll probably hit her more. Right now, she's around all of us," Skinner said.
"She's still probably going to be competing, so I'm sure she's trying to stay in the game, but honestly she's been the happiest person and I'm so grateful to see after everything she's been through that she's making the best of it."
Since cutting short her participation in the team final, the 19-time world champion said she is suffering from "twisties" -- a mental block that is preventing her from safely performing the high-risk skills required to compete.
Simone Biles, 24, has shared more details about her mental health issues and struggle with the 'twisties', an issue that causes gymnasts to feel 'lost in the air' and can result in horrific injury
She slammed those who have criticized her for pulling out of the team and all-around finals, insisting that her mental health struggles are real and very dangerous
