The team at the Trauma Center at Careggi Hospital performed thoracic surgery for the vascular injury, Ansa says. According to medical sources, Jason Dubaskwer remains in hospital in a very serious condition in the ICU with severe brain damage continuing.

The 19-year-old suffered a major head trauma, as well as a chest and abdominal trauma on Saturday afternoon at the end of a qualifying session for the Moto3 Italian GP. He was beaten while on the ground, after losing control of his machine when it came off a high-speed bend.

He was transported by helicopter to the hospital while practicing first aid for more than half an hour on the asphalt of the Mugello circuit to stabilize it, and Jason Dubaskwer underwent a scanner and MRI to verify that this was the most important area for urgent intervention.
