The Brazilian speared off the track and into the tyre wall at Turn 4 late in the Q2 session after debris, thought to be a suspension spring from the Brawn car of Rubens Barrichello, struck his helmet.
Medics were quickly in attendance and the start of Q3 was delayed as they extricated the Brazilian. After initial examinations at the medical centre, Massa, eighth fastest in Q2, was transferred to hospital for further checks
