He managed to prepare for the Tour well however and looked in great form until he crashed on stage 12 at high speed in a sprint finish. It was a chaotic crash where he was in the wrong place at the wrong time. Already it looked like something was wrong as he struggled to the finish, losing over 2 minutes, and the team decided to take him out of the race the next morning as it was no longer viable to fight for victory and realistically, the podium as well - which would likely be correct as Remco Evenepoel only looked strong later in the race.
Roglic initially was not diagnosed with any fracture but a couple of weeks later, an in-depth analysis revealed that he had indeed fractured a vertebrae. This puts his Vuelta a España presence into question, although even race director Javier Guillén came out to say
it was assured (and later retracted his words,
admitting he is in fact hoping for his presence).
This presence in the startlist of the Basque classic could be a positive sign if legitimate, but it is also necessary to take it with a grain of salt as it is visible in the list to see that Team DSM-Firmenich PostNL added sprinter Fabio Jakobsen as part of their team.
