Richie Porte will be out of action for at least four weeks after suffering a fractured collarbone and pelvis in a horror crash on stage nine which ended his participation in the Tour de France.
There was huge concern for general classification contender Porte when he lost control on a fast descent of the hors category Mont du Chat on Sunday and hurtled across the road to hit the mountain after coming off his bike.
The Australian, who collided with Dan Martin after going into the grass, received treatment as he lay on the ground and was taken to hospital for X-rays.
Porte's team, BMC Racing, later revealed that the 32-year-old Tasmanian sustained a broken right clavicle and also fractured his pelvis.
BMC's chief medical officer Doctor Max Testa said: "Richie Porte was transferred to the Centre Hospitalier Metropole Savoie in Chambery, where he was evaluated by Dr. Zerr.
"He underwent X-rays to determine the extent of his injuries. His condition was stable from the beginning, he was responsive and he remembered everything that happened before and after the crash.
"X-rays confirmed a non-displaced right clavicle fracture and a non-displaced right acetabulum fracture. Richie also suffered extensive superficial abrasions involving the right side of his body.
"At this stage, the injuries will not require surgery. The plan is to re-evaluate Richie tomorrow morning and confirm that he is stable enough to be transferred home."
Race leader Chris Froome was left with mixed feelings after seeing Porte and Team Sky colleague Geraint Thomas crash out on a brutal stage which was won by Rigoberto Uran.
The double defending champion, who finished third and holds an 18-second lead over Fabio Aru, said: "My thoughts go out to Richie and his team and I really hope he makes a speedy recovery.
"It doesn't get more eventful than that. Mixed feelings really, because of course I'm happy to still be in yellow, but to have lost Geraint Thomas with a broken collarbone and to see Richie Porte like that, even though he's a contender and a rival, that's never nice to see."
Froome also expressed his gratitude to former Sky team-mate Porte for the part he played in getting the GC contenders to slow down after Aru had attempted to steal a march by making an attack as the Brit stopped for mechanical assistance on the ascent of the Mont du Chat.
"I didn't actually see him [Aru] attack at that moment, I was too busy trying to sort out my bike," said Froome.
"I'm just grateful for that group waiting up. I think Richie was quite instrumental in there in saying 'listen, this isn't the time to attack, the leader of the race has got a mechanical problem'.
"Thankfully the group did ease up and I was able to get back to the front with my team-mates."
