The qualifying session for this weekend's Hungarian Grand Prix in Budapest has been halted following a hefty accident for Ferrari star Felipe Massa - with no confirmation as yet of the extent of the Brazilian's injuries.

After being struck on the helmet by a piece of flying debris towards the end of Q2, Massa shot off-piste and across the grass on the inside of turn four and embedded his Ferrari deep into the tyre barriers. It took some time for rescuers to be able to extract the S?o Paulista from his car, with the 28-year-old subsequently being transferred to the circuit's medical centre and then by helicopter to a nearby hospital.

The recovered F60 appeared to withstand the impact, with only mild damage to the nose and sidepod.

Initial reports suggest Massa may have escaped with only mild concussion and a knock to the chin, with subsequent footage showing that he had been hit by a piece of suspension suspected to have earlier broken off the Brawn GP of compatriot Rubens Barrichello.
