Luca Badoer has been drafted in as the temporary replacement for Felipe Massa for the European Grand Prix, after Michael Schumacher was forced to abandon his F1 comeback.
Schumacher had hoped to fill-in for Massa at the forthcoming races, but a neck injury picked up in a motorcycle accident has forced him to call off his F1 return.
As a result, Ferrari will promote its test driver Badoer to the race position for the next race in Valencia, as a reward for his many years of efforts with the team.
Ferrari president Luca di Montezemolo said: "I am very unhappy that a problem means that Michael cannot return to racing.
"In the past few days, I could appreciate his great efforts and extraordinary motivation which had spread through the team and fans around the world. No doubt his return would have been good for Formula 1 and I am sure it would have seen him fighting for wins again.
"In the name of Ferrari and all the fans, I wish to thank him for the strong attachment he displayed for the team in these circumstances.
"In agreement with Stefano Domenicali, we have therefore decided to give Luca Badoer the chance to race for the Scuderia after he has put in so many years of hard work as a test driver."
The 38-year-old Italian has been a Ferrari test driver since 1998 and last raced in 1999, for Minardi.
