Now, moving on, something really horrible now. Tragic accident that left one of our recent Rio Olympians paralyzed. Below the fighter that he is, BMX star Sam Willoughby is determined to walk again. Elite BMX riders need to be braised, determined, and also a little bit crazy. Sam Willoughby is all of those things, but he's also bloody gorge. He's one of the sport's brightest talents. Olympic silver medalist and a two-time world champion. But on Saturdays at Teber 10, he was training at Chula Vista, California, when tragedy struck. He was just doing a basic training session just within his warm-up and just looped out. Sam landed on his head, so there's been a lot of force through his spinal cord that's given him some compression. Willoughby was flown to hospital where surgeons took the drastic step of replacing his C6 vertebra with a titanium cage. Before fusing Sam C5 and C7 vertebrae with a plate and screws. It's an incredibly delicate process. He'll have less rotation in his neck in the future than he has now. But of course, the most important part has to be providing support for his spinal cord and decreasing the risk of any further injury. Sam has since regained feeling of movement in his arms and his progressing well. And now his aim is to walk fiance and fellow rider, at least post down the aisle.
