Kye Whyte of Britain was tended to by several paramedics before he was taken off the BMX track on a stretcher following a hard crash during the semifinals at the Paris Olympics on Friday night.
The reigning Olympic silver medalist, Whyte had just come down the steep starting ramp and into the 410-meter-long course near National Velodrome of Saint-Quentin-en-Yvelines when he went down.
He would have been going at about 35 mph at that point in the track, and landed hard on his side before coming to rest on the dirt.
Medical staff was tending to him even before Sylvain Andre of France led the field across the finish line.
