After an attempt on the vault that scored low, Simone Biles pulled out of the Tokyo Olympics for the day. However, there is no word about whether she will be competing Thursday. 

Her withdrawal was attributed to an "injury"; not much information was given about what the injury is, and to what extent it may have impaired her performance. 

"Simone Biles has withdrawn from the team final competition due to a medical issue," USA Gymnastics said in a statement. "She will be assessed daily to determine medical clearance for future competitions."

However, according to NBC commentators, the injury is mental, rather than physical. 

Simone Biles back in warmup gear, cheering on her teammates after she told them she pulled out of the team competition final.

“It is not injury related” and apparently her coach said “it’s a mental issue that Simone is having,” per NBC commentators just now. #TokyoOlympics pic.twitter.com/WdBgVBnF5m

After Biles won four gold medals and a bronze in the 2016 Summer Olympics, the women's gymnastics today is left to the Russians, who have been in fierce competition for the third gold medal in a row. 

Biles continued to cheer and encourage her teammates as she stood by.
