Lotto Belisol has been compelled to continue the Tour de France without Marcel Sieberg.

The German rider crashed hard in the descent of the Col de la Madeleine and has cracked his collarbone. After the race Friday an X-ray confirmed the presumed injury, a non-displaced fracture of the collarbone. Saturday morning Sieberg will fly back to Belgium where he will be operated in the hospital of Herentals during the course of the day. After the operation he should be able to restart training in a week’s time.
