Simone Biles does without the final of the floor exercise at the Olympic Games |  Voice of america

TOKYO – Simone Biles won’t defend her Olympic gold medal in floor exercise.

USA Gymnastics announced on Sunday that the six-time Olympic medalist decided not to compete on the floor, where she won gold in Rio de Janeiro and finished second in qualifying last week.

Great Britain’s Jennifer Gadirova will replace Biles in the final, which is scheduled for Monday.

USA Gymnastics said Biles has not yet made a decision about whether to attend the balance beam finals, which is scheduled for Tuesday. She won bronze at the event in Brazil five years ago.

Biles has already decided not to take part in the uneven bars and jumping finals, which are scheduled for Sunday evening at the Ariake Gymnastics Center. No medal was expected from her on parallel bars, but she is an Olympic champion in the jump.

Biles is dealing with a mental block called “The Twisties” in gymnastics. In other words, Biles has a hard time figuring out where her body is in the air in relation to the ground.

Biles was dominant in floor exercise throughout her elite career, winning five world championships along with her triumph in Rio. Their innovative tumbling has redefined the possibilities on the podium. She has two Tumbling Pass exits named after her in the sport’s point code.
