Sonny Colbrelli had to end his career after having been given an internal defibrillator after his collapse at the Volta a Catalunya.
Nathan van Hooydonck has now hung up his wheels for the same reason, and the Italian shared a message of understanding on the situation.
"I understand what's going through your head. I understand what you're feeling. I understand the pain. I understand your only question why me?" Colbrelli said in a Facebook post. "I know how it feels in that hospital bed while they tell you that your career will be 90% over, but in your head you don't want to believe it."
