CYCLING NEWS - Cavendish was taken to hospital during Wednesday's opening stage of the Tirreno-Adriatico in Italy.
The 32-year-old completed the stage but Team Dimension Data said he came down "pretty hard at around 55km/h".
"An X-ray found that he has a fracture of the seventh rib on the right side," added the team statement.
Cavendish, who has been selected by the Isle of Man to lead its road cycling team at the 2018 Commonwealth Games in April, did cross the finish line, but his time was outside the limit and is out of the Tirreno-Adriatico.
