Injured Formula One driver Felipe Massa could walk out of a Budapest hospital within 10 days and his eye appears to have suffered no damage in Saturday's accident, his doctors said on Tuesday. “My expectation is that he would walk out of the hospital on his own,” Peter Bazso, the medical director of the AEK hospital, told public television M1 on Tuesday. “If his recovery continues at this pace, I wouldn't rule out that he could leave within 10 days.” The Ferrari driver's condition remained serious, however, Bazso said. “I would like to point out that although he's recovering, this is not the end of the story; he is still in a life-threatening condition. Of course, the danger is decreasing by the day.” Dino Altmann, Massa's personal physician said the Brazilian was alert and his eyesight, a chief concern, was fine. “Today Felipe is improving continuously, he is more alert than he was before,” Altmann told reporters. “He's answering in three different languages in proper answers and he knows exactly what's right and left ... his left eye has no problem, his eyesight is okay,” Altmann told reporters. Massa fractured his skull in an accident during qualifying for the Hungarian Grand Prix when he was hit just above his left eye by a bouncing spring, weighing almost a kilo, that broke free from compatriot Rubens Barrichello's Brawn car. Schumi can come back Michael Schumacher would consider coming out of retirement if Ferrari asked the seven-time Formula One champion to drive for the injured Felipe Massa, his spokeswoman said Tuesday. “If Ferrari approaches Michael, he would think about it,” Sabine Kehm told German news agency DPA, but added that it was up to Ferrari to make the first move. Schumacher, the former Ferrari driver who holds nearly every record in Formula One, retired after the 2006 season.
