Ukrainian skeleton slider Vladyslav Heraskevych's disqualification from the Winter Olympics over his helmet depicting fellow athletes killed since Russia's full-scale invasion is the Games' biggest controversy so far.

Heraskevych was barred from the men's skeleton in Milan-Cortina earlier this week after he refused to stop wearing it and on Friday his appeal was denied.

He has said those featured on his helmet include teenage weightlifter Alina Perehudova, boxer Pavlo Ishchenko and ice hockey player Oleksiy Lohinov, adding that some of them were his friends.

More than 20 athletes appear on the helmet in total. Heraskevych stated that he would only compete if allowed to wear his 'helmet of remembrance,' a clear signal of his dedication to honoring the memory of those lost. The disqualification has sparked conversations about the intersection of sports, politics, and personal grief in the context of war.

While the International Olympic Committee (IOC) has strict rules about athlete uniforms and insignia, the emotional weight carried by Heraskevych's helmet raises questions about what is deemed appropriate in competition versus the need to remember and honor those who sacrificed their lives. This incident has drawn significant attention not only from fans but also from fellow athletes and political figures who support the acknowledgment of Ukraine’s ongoing struggles.

Overall, the situation illustrates the complex nature of sporting events amidst a backdrop of conflict, raising further discussions on how the global community should react to such displays of remembrance and identity.
