TOKYO (AP) — Reigning Olympic gymnastics champion Simone Biles is out of the team finals after apparently sustaining an injury during a vault.

The 24-year-old U.S. star huddled with a trainer after landing her vault. She then left the competition floor with the team doctor. Biles returned several minutes later with her right leg wrapped. She took off her bar grips, hugged teammates Grace McCallum, Sunisa Lee and Jordan Chiles before putting on a jacket and sweatpants.

The Americans will be forced to finish the rest of the competition without her, severely hampering their bid to claim a third straight Olympic title.

TOKYO (AP) — The Russian Olympic Committee has won the gold medal in women’s gymnastics after U.S. star Simone Biles exited with a medical issue. The ROC posted a team score of 169.528, ahead of the U.S. in second place at 166.096. The gold is the first for the Russians since the Unified Team triumphed in Barcelona in 1992 and came a day after the ROC men’s team edged Japan for the top spot in the men’s final. Great Britain won bronze.
