In brief
The decision by Ukrainian skeleton athlete Vladyslav Heraskevych to wear a helmet adorned with the images of athletes who have died since Russia's full-scale invasion has sparked significant controversy, leading to his ban from the Winter Olympics. The helmet, which he refers to as a 'helmet of remembrance,' features poignant tributes to fellow competitors, including boxers, weightlifters, and promising young talents, highlighting the human cost of war and the impact on Ukraine's sporting community.
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 - here's more on each of them.
