In April, she was chosen for the team competing at the 2013 European Artistic Gymnastics Championships in Moscow, Russia. During qualifiers she landed awkwardly from her Balance Beam dismount injuring her knee, and had to pull out of the competition. Her score qualified her for Balance Beam finals, despite the fall, but she had to return to the UK for medical assessment for her knee. The injury was later reported to be an ACL tear. Jupp had surgery in May and was out of competition for about a year. She told Hemel Today, "I kind of heard a snap but I didn't know how bad it was". She continued to say that she learnt a lot from her experience in Moscow and vowed to return to gymnastics when recovered.
