The British-based Force India team have signed Nicholas Latifi as their reserve driver for 2018.
Latifi, the 22-year-old Canadian who finished fifth in Formula One's feeder series Formula Two with the DAMS team last season, will take part in a number of Friday practice sessions this year.
British teenager George Russell had been in the frame for the role after impressing for Force India in practice at the final two rounds of last season in Brazil and Abu Dhabi.
But Force India were keen to ensure the 19-year-old, who is a member of the Mercedes young driver academy, would be available to them in the long term and that does not appear to be the case.
"I'm really excited about the opportunity," Latifi said. "Force India is a team that has shown constant improvement for the last few years and I'm proud to become a part of one of the success stories of Formula One.
"I am eager to show the team what I can do and help them as they continue to close the gap to the front of the grid."
