Jumbo-Visma director Richard Plagge decided to withdraw team leader Primos Rogerci before the final stage of the Criterium du Dauphiné, but said it was a precautionary measure and would not affect his preparation for the Tour de France, which starts in two weeks.

Roglic suffered a major crash on the final stage of the Dauphiné, but managed to finish the race and defend the race leader's yellow jersey.

"He hit his back hard and crashed. You have to be careful," Roglic said in Megève on Sunday morning after it was confirmed that he would not start the final stage of the Dauphiné.

Asked if the Slovenian rider, whose teammate reported feeling dizzy immediately after the crash, had suffered concussion, Plug explained: "He was dizzy, but it was because he hit the deck so hard that he asked, 'What happened? But after a few minutes he was fine mentally. I'm not worried about concussion."

Roglic's retirement was announced 24 hours after Tour de France rival Egan Bernal abandoned the Dauphiné due to a back injury and was later seen training.

"No, I don't think we will see Roglic training today," Plug said in response to a question about whether Roglic might follow the Colombian's example.

"I don't think it will interfere with Primosch's tour preparations.

Jumbo-Visma climber Sepp Kuss was also confident that Roglic would recover quickly from his injury.

"I think he will be fine. If he races with an injury, he could get hurt. But I think he's better than we thought," the American said.

Kuss said that Roglic was able to survive Saturday's fourth stage "probably because of the adrenaline. After the crash he still looked comfortable and was doing well."

Kuss added that Jumbo's leader realized the extent of his injuries after the race.

Prag also provided an update on Steven Kruijswijk, who fell earlier in the same stage and dislocated his shoulder.

Kruijswijk had said through his team that he would "decide next week if he will be able to compete in the Tour de France." Plug, however, refused to speculate after Roglic and Kruijswijk crashed heavily.

"He is now back home in Monaco. He dislocated his shoulder and caused a lot of road surface roughness. His shoulder is back to normal, but the road rash is really bad. Hopefully it will heal quickly," said Pluggi. [It's too early to say anything more because we have to see how he is tomorrow and the day after. These will be the crucial days to see how he recovers from his wounds."

Prag also admitted that DS Grischa Niermann of Jumbo Visma had spoken to race organizer ASO about the descent of the Col de Plan Bois, which Kruijswijk crashed and which team co-leader Tom Dumoulin described as "a disgrace."

"Grischa said something to the ASO. 'Usually the ASOs have their act together. In terms of safety, ASO, the Dauphiné, and the Tour de France are very good. On the other hand, this has happened more often in recent races. I think it is time to put safety in the hands of professionals."
