Renault remains in the dark about whether or not Robert Kubica will make a Formula 1 comeback next year - as it says it is still awaiting news on when the Polish driver will be able to drive a racing car again.
With team chiefs eager to formulate a plan for its 2012 driver line-up, Renault boss Eric Boullier says that plans to put Romain Grosjean in the car for Friday practice in Abu Dhabi and Brazil are part of an effort to look at other choices now.
"We have to assess options and we are still waiting for Robert to come back to us to say he can test," explained Boullier.
"The last information I have is that we will have to sit down and discuss how we can handle his [Kubica's] comeback, because I don't believe he can commit in the coming days. In the coming weeks maybe - but not coming days.
"So we have to make sure that we work together on a plan for him to come back. But I still need to have a proper plan to make sure that, which I don't wish, if he is not coming back how we go forward in a good way."
Although Boullier says Kubica's management team remains confident he will race in F1 again, no final decision can be taken until he has actually tested.
Boullier added: "We have everything ready. The 2009 cars are ready in the garage, ready to fire up. We are ready for him but we are waiting for him to tell us he is ready.
"I know they are very confident and I am happy about this, because I am the first one wishing to have Robert back in the car, but nobody knows.
"Nobody has a medical report and nobody has seen him driving a car and being at speed. Until we see him and have the confirmation then, we can not say anything. And we need to keep, unfortunately, the option of not having him back.
"I am in regular contact with his manager, but until he is driving the car we do not know."
