Simone Biles withdraws from women’s gymnastics team final

After a rare stumble on her first vault, American gymnastics star Simone Biles withdrew from the team competition, leaving Team USA’s Suni Lee, Jordan Chiles and Grace McCallum to finish the event. Biles, the reigning Olympic champion, pulled out “due to a medical issue,” USA Gymnastics said in a statement Tuesday.

All eyes were on Biles, considered the greatest gymnast in history, to see if she would attempt a Yurchenko double pike on vault. Instead, she bailed in the middle of her Amanar attempt, bringing down the difficulty level of her vault. Her score of 13.766 was remarkably low for Biles. Afterwards, Biles left the competition floor.
