In a short statement, Ferrari has revealed that the surgery Felipe Massa has received for damage to his skull sustained in an accident during qualifying for this weekend's Hungarian Grand Prix has been 'positive'.

The Brazilian was struck on the helmet by a piece of suspension that had flown off the Brawn GP of compatriot Rubens Barrichello towards the end of the Q2 phase of the session, knocking him unconscious and causing him to veer off the circuit and into the tyre barriers at high speed.

After being extricated from his car, the 28-year-old was taken first to the Hungaroring's medical centre and then airlifted to the AEK Hospital in nearby Budapest, where he is being treated for skull damage, a cut to his forehead and concussion [see separate story - click here].

'Felipe Massa has undergone surgery this afternoon at the AEK Hospital in Budapest, and the outcome of the procedure was positive,' read the statement issued by the Scuderia. "Now, Felipe will remain under observation in intensive care. An update on his condition will be issued late tomorrow morning.'

The Maranello-based outfit also confirmed that Massa will not be racing on Sunday.
