Olympic officials had told Vladyslav Heraskevych that the helmet, featuring images of Ukrainian athletes killed in the war with Russia, violated the Games' ban on political speech.
The International Olympic Committee has disqualified a Ukrainian sled athlete over his refusal to remove images of war dead from his helmet in competition.
Heraskevych came to the Olympics with a customized helmet showing the faces of more than 20 Ukrainian athletes and coaches who were killed during the war, a conflict that started shortly after the 2022 Beijing Games ended.
