Rodolfo Gonzalez will make his grand prix debut this weekend when he contests Friday's first practice in Bahrain for the Marussia team.
It will be the Venezuelan's drivers first outing for Marussia having previously been in action for Caterham and Force India.
The 26-year-old, who is scheduled to take part in "several" appearances this season, will replace Jules Bianchi in FP1.
"I'm really happy with this opportunity to drive in my first FP1 session of the season," said the Marussia reserve.
"It will be a nice feeling to be back in a car - especially to drive a Formula 1 car again - and with my previous F1 experience I feel more than comfortable and ready.
"I love this circuit, it will be quite dusty in FP1 but it's also good fun and I'm looking forward to seeing what I can achieve.
"I would like to thank the team for their faith in me. They have made me feel so welcome and have bent over backwards to involve me in every aspect of the racing."
