SOCHI, Russia — The Russian freestyle ski federation says Olympic athlete Maria Komissarova has undergone another surgery in Germany on her fractured spine.

Komissarova had immediate surgery at a hospital in Krasnaya Polyana following Saturday’s skicross accident and was airlifted to Germany the next day. The surgery in Germany was on Monday, and doctors say the Russian’s condition is grave but stable.

State sports bodies and the federation paid for Komissarova’s transfer to Germany and her initial treatment there, but the federation says the skier’s recovery may take a long time and extra money will be needed.
