Team Sky's Edvald Boasson Hagen has abandoned the Tour de France after suffering a broken shoulder blade in a fall at the end of stage 12.
The Norwegian was caught up in a high-speed crash on the run into Tours as the peloton prepared for the bunch sprint.
Despite remounting and riding to the finish, Boasson Hagen was visibly in pain and medical checks revealed a fracture to his right scapula.
The 26-year-old had finished second behind Mark Cavendish on stage five and was set to play a crucial role in helping Chris Froome's bid to win the yellow jersey later in the race.
Team Sky doctor Alan Farrell told TeamSky.com: "After the crash, Edvald was taken to a local medical centre for X-rays, which revealed he had a fracture of his right scapula.
"Fortunately, this doesn't require surgery, but Edvald will return home to Norway for further investigation and treatment and we look forward to seeing him racing again sometime over the summer."
Team principal Sir Dave Brailsford added: "It is a real shame for Edvald and a setback for the team that he has been forced to abandon the race.
"It is never nice to lose a rider of Edvald's ability, but ultimately we are still confident that with the riders we have got left we can pull together and see the race through.
"The plan doesn't change and we will do everything we can to support Chris [Froome]."
Team Sky are now down to seven riders after Vasil Kiryienka was eliminated for missing the time limit on stage nine.
