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. Each represents the human cost of a brutal conflict that has claimed lives and disrupted countless futures.

The helmet was meant as a gesture of remembrance, symbolizing the profound loss felt within the Ukrainian sports community.

This controversy has sparked a larger conversation about remembrance in sports and the importance of honoring lives lost in the fight against adversity.
