After having exited the women's gymnastics team final on Tuesday, and then quitting the individual all-around final scheduled for Thursday, America's superstar gymnast Simone Biles has now decided not to compete in the Tokyo Olympics finals for two of the four individual women's gymnastics events, vault, and the uneven bars.

A CNN report quoting USA Gymnastics said that Biles has cited mental health concerns as she attempted to protect her body and mind, as the reason for the withdrawal.

Among the top favorites to win big in these events, Simone Biles had said earlier that she was wary of her positioning midair, which was a significant concern.

Biles, who has won every individual all-around competition she had entered since 2013, will continue to be evaluated daily to know if she would compete in the finals for floor exercise and balance beam. The women's vault and bars finals have been scheduled for Sunday, while the women's floor final will get underway on Monday. The beam final is Tuesday.

In place of Biles, it would now be MyKayla Skinner, who will be competing in the vault finals for the U.S.. Compatriot Jade Carey will play alongside.

U.S. men's fencing team wear pink masks to protest against team mate's inclusion

In a significant development, Team USA's men's fencing team members too out a unique protest against a teammate. According to NPR, the men's fencing team wore pink masks for their opening match as a show of support for sexual assault victims. They were protesting against teammate Alen Hadzic who has been accused of sexual misconduct.

Hadzic was chosen to represent the U.S. at the Tokyo Olympics, and team members Jake Hoyle, Curtis McDonald, and Yeiser Ramirez wore pink masks to proclaim their displeasure.

Hadzic has been accused of sexual misconduct between 2013 and 2015 by three women, the report added.

Hadzic denied these allegations and successfully appealed a suspension that would have dumped him from the U.S. team. Hadzic was suspended from all fencing activities by the U.S. Center for SafeSport, an independent agency investigating sexual abuse in Olympic sports. However, an arbitrator ruled that the suspension was "inappropriate to the allegations."
