Belgian triathlete Pieter Heemeryck will not be able to compete in the Ironman New Zealand scheduled for Saturday.
The triathlete was hit by a car during a training session on Thursday.
Hospital examinations revealed that he broke his right collarbone in the accident, which occurred near his apartment.
The 35-year-old from Leuven aimed to qualify for the next Ironman final in Nice this weekend.
For the rest of the season, he will focus primarily on the T100 circuit, with the Challenge Roth in Germany on 6 July as a key event.
