Mercedes-backed GP3 champion George Russell will carry out practice running with Force India in Brazil and Abu Dhabi.
Russell, 19, joined Mercedes at the start of the year, having impressed in European Formula 3 in 2016, and clinched the GP3 title in his rookie campaign, wrapping up the crown with a round to spare.
Russell made his public Formula 1 test debut with Mercedes during in-season running at the Hungaroring, when he got behind the wheel of the W08 for two days.
Russell will now link up with Force India to carry out FP1 sessions in Brazil and Abu Dhabi, the former in place of Sergio Pérez, and the latter in place of Esteban Ocon.
“I’m extremely excited to be driving in free practice for Force India in Brazil and Abu Dhabi,” said Russell.
“2017 has already been a year full of great opportunities and to top off the season with these two outings feels fantastic.
“I’ve never driven the VJM10 before or driven at Interlagos, but I’m really looking forward to the challenge.”
Force India has already retained Perez and Ocon, who is also backed by Mercedes, as its 2018 race drivers.
Sauber's Pascal Wehrlein, yet to confirm his plans for next season, is also part of Mercedes' roster.
