After Simone Biles finished up her balance beam routine on Sunday, she appeared to suffer a possible injury to her ankle. It seemed as if the ailment was bothering her during warmups for the floor exercise routine.
As Biles got on the mat to perform her ground routine, her left ankle/lower leg was wrapped, and she came off the mat after completing her performance appearing to walk somewhat gingerly on that leg. She sat at a chair with her leg pulled up.
