Having crashed out of the general classification lead on the stage 10 time trial at the 2014 Vuelta a Espana, Movistar's Nairo Quintana was forced to abandon the race and his hopes of a second grand tour victory this year after crashing again on stage 11.
On-bike footage of the crash has since emerged, seemingly from one of the Saxo-Tinkoff bikes, and while it gives a perspective of the crash, it fails to shed any light on what caused the incident in the first place.
The Colombian has since had successful surgery on the shoulder injury sustained in the incident, with his team announcing that he had been released from hospital in Pamplona on Friday.
