Tasmanian Formula 3 driver Alex Peroni is in hospital in a stable condition after a "heavy crash" at the Autodromo Nazionale di Monza.
The 19-year-old Hobart-born driver remains under observation after breaking a vertebra and did not take part in the second race at the Italian Grand Prix, a statement from Campos Racing said.
Peroni was on the 20th lap when he "took flight on the sausage curb", the statement said, "but walked away from the incident and was taken away in the medical car for the usual checks".
"Alex's life was saved by the halo, his helmet and the robust modern survival cell," the statement said.
"Alex is currently in hospital and he has been immobilised until further scans are performed on his back on Sunday.
"His D6 vertebra has multiple fractures and the medical staff will decide tomorrow if it's necessary to operate.
"Alex is also recovering from concussion, with his helmet extensively damaged."
Peroni posted on social media from his hospital bed saying: "That was a big one".
"Not sure of the recovery time but hope to be back in the car as soon as possible," he said.
"Thanks everyone for the messages and support I really appreciate it."
Peroni, a Formula 1 aspirant, has been racing in lower categories since 2015 after a very successful eight-year career in karting.
He is placed 20th in this year's championship driver standings.
