Dupasquier, in his second season in Moto3, fell and was struck by another bike, before sliding along the track, during Saturday qualifying.

Doctors rushed to the scene and after attending to him for 40 minutes on the circuit had him airlifted to Florence’s Careggi hospital.

The teenager underwent chest surgery overnight “for a vascular lesion” and had suffered “severe brain damage”, a hospital spokesman told AFP earlier Sunday.

His team, Pruestel GP, had already pulled out of Sunday’s race.
