American gymnast Simone Biles was forced to withdraw from the team gymnastics competition in Tokyo.
Cameras showed Biles walking with a team doctor with her foot heavily wrapped.
Biles, 24, left the arena floor following the vault competition and returned to inform her teammates of her status before donning her warmup apparel.
Biles earlier this week addressed via social media the weight she was feeling at the Olympics and pressure to live up to the greatness labels applied by fans and media.
Jordan Chiles replaced Biles on the second floor rotation, which is the uneven bars, after commentators pointed out Biles did not complete the vault routine she intended.
Team doctor Marcia Faustin escorted Biles backstage before Biles re-entered the floor area to embrace teammates Grace McCallum, Sunisa Lee and Chiles.
The all-around final, which is scheduled for Thursday, could also be in jeopardy.
Biles qualified for the finals in all individual events in Tokyo.
She took home five medals at the 2016 Summer Games.
