Kubica still in running for Renault race seat
Originally, team boss Eric Boullier imposed a rigid mid-October deadline for the injured Pole to let him know if he will be able to race next season.
That deadline has now passed, but Frenchman Boullier admitted in Korea that he has agreed to wait a little longer.
The new deadline is the "end of October", he is quoted by Germany's motorsport-total.com, "and maybe even longer."
It seems the deadline is a moving target.
"It also seems that way to me," smiled Boullier, "but if Robert can go back to formula one, then I want him to drive for us. So I have to give him a chance.
"We will be flexible to the point where we cannot."
Boullier does not deny that a time will eventually come when he has to overlook Kubica for the good of the team.
"No, no, I will not act against the interests of the team," he insisted. "If I see that something is going wrong with next year's driver lineup, we must make a decision."
Vitaly Petrov, Bruno Senna, Romain Grosjean, Rubens Barrichello and others are reportedly also all in the running to race for the team in 2012.
Boullier said in Japan recently that he intended to call Kubica in the next few days.
"I spoke with (his manager) Daniele Morelli," he revealed. "They are very confident that Robert will return, which is good to hear."
Boullier said the 26-year-old is in the midst of his rehabilitation process but could be ready to sit in a driver simulator "perhaps within a month".
