Biles explained she has to focus on her mental health, which is important any day of the week, but for a gymnast absolute concentration is crucial because getting hurt is so easy. So I don't blame her one bit.She just announced that the withdrawal was not related to an injury. Her participation in future events is TBD. In all honesty, this has been a long time in the making. As I noted above, she was barely keeping it together all the way back at the trials. You could tell something was not right with her. It will be interesting to see if she competes in the all-around as it may be less pressure than the team event, which has become the most anticipated event in the whole Olympics from a US standpoint.
