The World Is Gutted By Simone Biles' Withdrawal From Team Competition

"We hope this isn't the last we've seen of one of the world's best gymnasts," the Tokyo Olympics Twitter account wrote.

Biles, the face of not only gymnastics but perhaps of the entire Summer Games, performed a vault and walked off the floor.

USA Gymnastics said she had pulled out of the competition “due to a medical issue” and will be assessed daily. Biles later cited “mental health” concerns.

“We hope this isn’t the last we’ve seen of one of the world’s best gymnasts,” the Tokyo Olympics’ Twitter account wrote ominously.

“I feel sick to my stomach; it’s horrible,” former Olympic teammate Aly Raisman told “Today.” “I’m obviously praying that she’ll be able to compete in the all-around final.”

Crushed fans and some celebs chimed in as well.
