British cyclist Mark Cavendish suffered a fractured rib and facial injuries in a crash on the opening stage of the Tirreno-Adriatico in Italy.
Cavendish, 32, persevered to complete the stage but X-rays subsequently confirmed a fracture to his seventh rib on his right side.
Cavendish, who withdrew from the Abu Dhabi Tour in February after suffering concussion and whiplash, will play no further part in the Tirreno-Adriatico as he finished the stage outside the time limit.
In an interview reported on BBC, Cavendish said: "It's frustrating to have crashed, particularly in light of the concussion that I sustained in Abu Dhabi.
"But I'm just pleased that there's no major damage done.
"Despite the pain from my injury I was really looking forward to a fast second stage and naturally disappointed that I'm not going to be a part of it."
