Sep.10 (GMM) Jean-Eric Vergne is unhurt after Sunday's incident at Monza.
Toro Rosso is investigating why the French rookie's Ferrari-powered car suddenly veered out of control at the end of Monza's front straight during the Italian Grand Prix.
The high-speed incident launched Vergne's car over a kerb, "And I count myself lucky that the car did not flip over", he said.
He did, however, land with a bump, and immediately complained on the radio of a sore back.
"I was taken from the accident to the medical centre," explained the 22-year-old, "but apart from a bit of pain in my back and my head, I am fine."
