Spanish rider Angel Vicioso, injured in a fall on the ninth stage of the Tour of Italy, will take no further part in the race, his team, Katusha, announced on Monday.
The 36-year-old former Giro stage winner suffered three broken ribs, a wrist fracture, a damaged left shoulder and bruising to his right side during the crash on Sunday.
He managed to finish the stage in Florence in 177th position at the back of the main peloton.
Monday was a rest day for the riders before Tuesday's 167-kilometre 10th stage from Cordenons in northeast Italy to Montasio.
Italy's Vincenzo Nibali is currently the race leader, ahead of Australia's Cadel Evans and Dutch rider Robert Wiggins. Last year's Tour de France winner, Bradley Wiggins of Britain, is 1min 16secs back in fourth.
