Stefano Coletti has been taken to hospital with back injuries following his crash in the first GP2 race of the weekend at Spa.
The Trident driver had to be extricated from his car by doctors after he ran over the back of Mikhail Aleshin's Carlin car shortly after a rain shower had hit the circuit.
Coletti's car went up in the air as it went over Aleshin's rear wing, and the impact as he landed is suspected to have compressed some of the vertebrae in his back.
If the Monaco driver has suffered those injuries, he would not be the first in GP2. Jules Bianchi and Ho-Pin Tung suffered a similar fate with aerial accidents in 2010.
