Michael Schumacher has announced that he will not be able to stand in for injured Felipe Massa at Valencia race this month due to physical reasons.The decision comes after several medical check ups following his testing in a two year old Ferrrari car.Schumacher suffered a heavy crash in february during a practice session in bike racing and has failed to regain physical fitness demanded by the standards of F1.

Schumacher reacted saying

"My doctor had told me that we could do this test and then, after a
short break, add some more stress to see how the situation developed. In the end
we've done everything we could do, but it didn't go as we wanted."
