Apparently the injury isn't as bad as first thought. He doesn't have a broken collarbone, but a dislocated collarbone. They'll put it back tonight, and expect him to ride a bike in 2 weeks. This was said by Patrick Lefevere.
Hectische dag bij Soudal-Quick Step. Na de val van Remco Evenepoel was het wachten op een update over de medische balans. Ploegmanager Patrick Lefevere dacht even dat de tol nog zou meevallen, maar dat bleek niet het geval.

Yeah, but he also has a broken rib, a broken shoulder bone and a broken bone in his hand. His collarbone might not be broken and only dislocated but next to that he also has 2 bruised lungs.

Edit: The title of the article that Berniece posted above is: "Patrick Lefevre had false hope for a moment that the injuries weren't that bad"'
Clearly, you didn't read the article or your translation didn't work. But it's pretty clear that he won't ride in 2 weeks.
Lefevre thought he could be back on the bike in 2 weeks but that was before they learned of the other 3 broken bones and his lungs
