According to L'Equipe, it's "une déchirure partielle à l’adducteur de la jambe droite" - partial tear of the adductor in the right leg

When Artur Verner is saying/writing something you always have to expect a lie as we've known for many years.
Nathalie said she held the press conference because many people wanted to know how Fabian is doing and if they can go to Worlds. So instead of having 15 individual interviews she preferred to answer all questions at a press conference. It was very unprofessional of the TV commentator to start a rumour out of that.
Thanks for the answer and YIKES for Fabian!!
