Olympic champion Simone Biles has pulled out of the gymnastics team finals due to an apparent injury.
The record-breaking American athlete had a rocky start in the final, where the US is looking to secure a third straight Olympic title.
The 24-year-old bailed on her planned Amanar vault, opting for an easier one in mid-air, and then struggled with the landing.
The rare misstep allowed the gymnasts from Russia to open up a one-point lead after the first rotation.
Vault has long been a strong suit for the US and Biles is the defending Olympic and world champion in the event.
Biles had opened up about the pressure she feels this Olympic Games.
On Sunday she said she had “the weight of the world on her shoulders”.
