Marussia reserve driver Rodolfo Gonzalez will replace Max Chilton in Friday's first practice for the Spanish Grand Prix.
The 26-year-old, who is backed by Venezuelan oil company PDVSA, joined Marussia at the start of this season and made his debut at a grand prix weekend last time out in Bahrain.
Gonzalez replaced Jules Bianchi for the opening practice at the Sakhir circuit and finished bottom of the timesheets, eight-tenths behind Chilton.
However, for this weekend's Spanish GP it is the Brit he will replace, contesting first practice at the Barcelona circuit alongside Jules Bianchi.
Chilton will be back in the car for FP2.
