Jason Dupasquier: 19-year-old Moto3 rider dies after crash in Italian GP qualifying

19-year-old Moto3 rider Jason Dupasquier has died following a serious crash in the Italian GP qualifying session on Saturday.

The Swiss rider was involved in an accident with riders Ayumu Sasaki and Jeremy Alcoba towards the end of the 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.

The 19-year-old was airlifted to the Careggi hospital in Florence with serious injuries to his head and chest. It was confirmed on Sunday he had died from those injuries.
