Lauren Mitchell (AUS)
Lauren Mitchell is Australia’s most decorated gymnast with three world medals in her repertoire as well as two Olympics: Beijing 2008 and London 2012. However since London Lauren has been plagued with injuries, the most recent was a torn ACL that required a full right-knee reconstruction.
Lauren was forced to miss the Test Event, and her presence might have made a huge difference since the team finished 5th in a competition where only the top four teams would earn team berths. Lauren was present at the Australian Nationals but the sole spot went to her 2012 Olympic teammate Larissa Miller.
Lauren has not made a final decision regarding her career and could potentially want to stay in the sport to have a chance to compete at home for the 2018 Commonwealth Games set to take place in Australia.
Viktoria Komova (RUS)
Viktoria remained absent from the sport for three years after her London 2012 silver medal in the all-around. In numerous ocassions she attempted to comeback but was hampered by either illnesses or injuries. In 2015 she finally returned to the World stage and became 1 of the 4 Uneven Bars World Champion in Glasgow.
In early 2016 Viktoria was removed from contention for the European Team due to back problems and in June she announced she had completely stopped training due to her back issues. While she wants to continue in the sport it will depend on her medical prognosis.
Ksenia Afanasyeva (RUS)
The two-time Olympian and 2011 World Floor Champion was limited to only vault at the European Championships due to a foot injury that required surgery. She was named alternate to the Olympic Team but with high hopes of upgrading her status to Olympic Team Member as she is very much needed in the Floor Exercise where Russia is very weak. But in an abrupt end for Ksenia she was forced to withdraw completely but not due to her injury but due to kidney problems that require medical attention and recovery time
Liu Tingting (CHN)
The new senior was named to the Chinese Olympic as its youngest member and most inexperienced one however a hand injury forced her to withdraw. Unlike many of the gymnasts in this list her youth gives her a lot of hope, as she’s likely to have a second chance in Tokyo 2020. Liu has been replaced by two time World Team member Tan Jiaxin.
