Reigning Olympic champion Simone Biles is out of Tuesday's team finals because of a "medical issue," according to USA Gymnastics.
The 24-year-old U.S. star, considered to be the greatest gymnast of all time, huddled with a trainer after landing her vault. She then exited the competition floor with the team doctor.
Biles returned several minutes later. She took off her bar grips and hugged teammates Grace McCallum, Sunisa Lee and Jordan Chiles before putting on a jacket and sweatpants.
"Simone has withdrawn from the team final competition due to a medical issue," USA Gymnastics said in a statement.
