Russian youngster Sergey Sirotkin will make his grand prix debut during Friday practice for his home race in Sochi, Russia next month.
The 19-year-old is part of Sauber’s driver development programme and had been expected to land a full-time seat this season thanks to Russian investment in the team. That however failed to materialise and he has since been sidelined, competing in Formula Renault 3.5.
However the Russian tweeted that he would be behind the wheel of the C33 on October 10th – the Friday of the Russian race.
He has some experience of the car when he took part in the Bahrain in-season test earlier this year.
