Force India has confirmed that test and reserve driver Alfonso Celis Jr will replace Nico Hulkenberg this Friday's Russian Grand Prix FP1.
The 19-year-old Mexican is contracted to Force India this season with seven Friday Grand Prix outings scheduled this year.
Celis already took part in a free practice session at Bahrain in place of Sergio Perez, so it appears Force India's regular drivers are taking turns in standing down.
Celis Jr is currently racing in the Formula V8 3.5 Series in which he lies ninth, having failed to score at least a podium finish up to now.
The Russian Grand Prix in Sochi will see two reserve drivers participate in Friday's morning session, with Celis joined by local boy Sergey Sirotkin driving for Renault.
