On Saturday, 25 July 2009, in the second round of qualifying for the Hungarian Grand Prix at Hungaroring, Ferrari driver Felipe Massa's head was injured, though protected by his driver's helmet, he was struck by a suspension spring that had fallen from Rubens Barrichello's Brawn GP car while driving at high speed. He was knocked unconscious, and subsequently crashed head-on into a tyre barrier. Massa was thereafter airlifted to the ÁEK hospital in Budapest, where he underwent surgery in the area surrounding his left eye. His condition was initially described as "life-threatening but stable", but improved rapidly. Massa was discharged from hospital the following week and returned to Brazil. After further tests it was decided that Massa needed a titanium plate inserted into his skull to strengthen it for racing in Formula One again.
