The Australian was amongst a small group of GC contenders including race leader Chris Froome (Team Sky) when he crashed on a corner of the treacherous descent from the final climb of stage nine.
He took out Dan Martin (Quick-Step) in the incident, but looked to suffer severe injuries as he collided with a stone wall on the opposite side of the road to where he fallen from his bike.
But Porte fortunately remained conscious and remembers the incident clearly according to his team, with a fractured pelvis and clavicle the worst of his injuries.
Porte, who sat fifth overall at the time, was immediately treated by Tour medical staff on the roadside before being transferred to hospital for X-rays.
"Richie Porte was transferred to the Centre Hopitalier Metropole Savoie in Chambéry where he was evaluated by Dr. Zerr," a BMC statement from the team doctor on Sunday evening read.
"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."
Porte will now have to have around four to six weeks off the bike in order to recover, meaning it's likely he won't be able to return for the final Grand Tour of the year, the Vuelta a España.
The team will decide on his race schedule at a later date when Porte's recovery has progressed.
"Normally, a fractured clavicle and pelvis would require four to six weeks' recovery, providing there are no complications," the BMC statement said.
"If everything goes to plan, Richie could be back on the bike at the beginning of August and slowly build his fitness up from there.
"Based on Richie's recovery, we will re-evaluate his program for the rest of the season in consultation with BMC Racing Team management."
