Ferrari team principal Stefano Domenicali has admitted to the team's website that they wanted to sign Robert Kubica for 2014.
Kubica last raced in 2010 and was in the form of his life for Renault before an awful accident in a rally event prior to the 2011 season left him with multiple injuries to his hand and arm.
Domenicali revealed: "We were keeping an eye on him. Unfortunately, I don't think he will be back, because with his physical problem, he would struggle in certain limited situations which require reactivity. It's a shame."
The Pole has recovered sufficiently to compete in the World Rally Championship but single-seater cars require different types of reactions, and the cockpits have far less room.
Despite a series of successful operations, it is now looking increasingly unlikely that Kubica will ever be able to return to Formula 1.
He competed in 76 races before his accident, claiming one pole and one win in Bahrain and Canada respectively - the victory coming a year after a frightening accident at the same venue.
Domenicali also went on to clarify the current situation with Fernando Alonso after his public criticism of the team, saying: "If I have something to say to him, as would be the case with my engineers, I would do it behind closed doors and in a harsh manner.
"But externally, I will always defend the team. When he crossed the line, president Montezemolo intervened and in private. So did I."
Ferrari head into this weekend's Indian Grand Prix in the lead in the battle for second place, 10 points ahead of Mercedes and 33 clear of Lotus.
