MILAN, Feb 12 : The ejection of Ukrainian skeleton racer Vladyslav Heraskevych from the Winter Games over his "helmet of remembrance" has put the spotlight on rules over where athletes are not allowed to express themselves on political matters at the Olympics. Heraskevych was barred and stripped of his accreditation minutes before competition was due to start at the sliding venue on Thursday. The helmet depicts two dozen Ukrainian athletes killed since Russia's invasion of the country in 2022.
