The owner of the Renault Fomula One team says Poland's Robert Kubica is sure to miss the entire racing season but might be able to take part in a practice session at some point.
Gerard Lopez, the Renault F1 chairman whose Genii Capital last year bought out the French carmaker, says nobody could predict how well the driver would recover from the rally accident he suffered in February.
Kubica's former Sauber team mate Nick Heidfeld is standing in for the Pole at Lotus-backed Renault alongside Russian Vitaly Petrov.
The 26-year-old Kubica spent two months in hospital after suffering life-threatening arm, leg and hand injuries while competing in a minor rally in Italy.
The team said earlier this month that doctors considered the first stage of his recovery to be finished and he was now entering a new phase of rehabilitation.
