The Polish Formula One driver Robert Kubica has had a further small operation as he enters a new phase of rehabilitation three months after his career-threatening rally accident.
His Renault team said on their website that doctors now considered the first stage of the driver's recovery to be finished.
Kubica spent two months in hospital after suffering life-threatening arm, leg and hand injuries while competing in a minor rally in Italy in early February.
The Renault statement added more small operations are planned to remove the unavoidable adhesions that are affecting the functionality of his forearm and elbow muscles.
Renault team boss Eric Boullier went to visit Kubica in Italy after Sunday's Turkish Grand Prix and reported that the doctors were pleasantly surprised by the improvement in the 26-year-old's condition.
He says Kubica had been keeping in regular contact with his engineers about developments at the team.
However the Frenchman warned it could be mid-June before the team had a clearer picture of Kubica's prospects.
Germany's Nick Heidfeld is standing in for the Polish driver at Renault alongside Russian Vitaly Petrov.
