American BMX rider Connor Fields was taken to the hospital on Friday at the Tokyo Olympics after a scary crash during the men's semifinal heat.
The crash occurred on the first turn of the race, just nine seconds in, as Fields collided with two other bikers while landing from a jump. Fields appeared to hit the back tire of another biker.
As he fell, he caused something of a pile-up as other riders crashed into him. The other riders appeared to be okay.
Fields was treated by medical staff before being taken to the hospital. There were no further updates on his status.
The Olympics Twitter account wished Fields and women's rider Saya Sakakibara, who was involved in a crash, well.
