FLORENCE, Italy — Swiss motorcycle rider Jason Dupasquier has died following a crash during Moto3 qualifying for the Italian Grand Prix, the Careggi Hospital in Florence announced Sunday. He was 19.

"Despite the best efforts of circuit medical staff and all those subsequently attending to the Swiss rider, the hospital has announced that Dupasquier has sadly succumbed to his injuries," MotoGP said in a statement.

Dupasquier was involved in an accident with Ayumu Sasaki and Jeremy Alcoba toward the end of Saturday's session, which was immediately red-flagged.

Dupasquier appeared to fall and was then hit by his own motorbike and that of Sasaki, while a visibly shocked Alcoba later said on television that he thought he had also gone over the Swiss rider's legs.

He was treated on the track for approximately 30 minutes before a helicopter landed and airlifted him to a hospital in Florence.
