Catty Comments with sad news. As suspected, Anna Li strained a lower abdominal muscle in training after arriving in Tokyo. Via IG2, she has been named the alternate for Team USA.
Anna did train on bars during podium training but was off on her Shaposhnikova. Her interview with Gymnastike after podium training is below.
Her absence will really weaken Team USA on bars and put them farther behind both China and Russia with much lower D scores. However, if there is a bars disaster in qualifications, for this FIG event (and not during the Olympics), Anna as the official alternate is still eligible to compete on bars in TFs.
