The four-time Olympic champion left the competition area on Sunday after performing on her first apparatus, the balance beam, but returned to complete her routines on the floor exercise, vault and uneven bars with her left leg and ankle wrapped at the qualifying session.
Despite the nagging pain, Biles was dominant, leading the US to a huge win in team qualifying while also qualifying first in the all-around before an ecstatic, star-studded crowd at the Bercy Arena.
"Last night was, oh my God - epic," Nellie Biles said.
"I mean the energy in the stadium was unbelievable. The girls did such a wonderful job and you couldn't ask for anything better."
She added she felt "relieved" after the team's performance, and that she had spoken to her daughter, who said she was doing well and heading to practice on Monday morning.
Biles is leading a US team on a self-described redemption tour after Biles abruptly pulled out from the team final at the Tokyo Games suffering from the 'twisties', a term used to describe the temporary loss of spatial awareness while performing high-difficulty elements.
The USA are heavy favourites to win gold in the team final on Tuesday.
