Michael Schumacher has cancelled his Formula One comeback as a result of a neck injury he suffered earlier this year in a motorcycle crash.
In a statement issued on his website, Schumacher said that he informed Ferrari last night he was not fit enough to race.
"Yesterday evening, I had to inform Ferrari president Luca di Montezemolo and team principal Stefano Domenicali that unfortunately I'm not able to step in for Felipe," he said.
"I really tried everything to make that temporary comeback possible, however, much to my regret it didn't work out.
"Unfortunately we did not manage to get a grip on the pain in the neck which occurred after the private F1 day in Mugello, even if medically or therapeutically we tried everything possible."
"The consequences of the injuries caused by the bike accident in February, fractures in the area of head and neck, unfortunately have turned out to be still too severe.
