Red Bull junior Juri Vips will enjoy his official F1 debut in Barcelona, with the F2 charger taking over Sergio Perez's car in Friday's first practice session.
This year, F1's sporting regulations mandate that teams must assign a rookie driver - or a driver who competed in no more than two F1 world championship rounds - to at least two practice sessions.
Red Bull has logically decided to entrust its RB18 in Friday's session to Vips, its first-in-line young hopeful.
The Estonian has sampled F1 machinery in the past, with Red Bull running Vips in F1's end-of-season young driver tests in Abu Dhabi, while he has acted as a reserve driver for both Re Bull and sister outfit AlphaTauri.
Vips will enjoy a busy weekend in Spain as he'll also be racing with his regular team Hitech in the FIA Formula 2 Championship.
The 21-year-old currently sits sixth in the series' standings after three rounds.
Vips won't be the only new driver taking part in Friday's FP1, with Williams assigning Nyck de Vries to the session.
Furthermore, Alfa Romeo reserve Robert Kubica will also be behind the wheel of the Swiss outfit's C42 on Friday.
