Alexander Albon will start the Russian Grand Prix from the pit-lane Red Bull fitted a new floor to his car following a crash in qualifying.
Albon had been due to take a five-place grid drop due to Honda introducing a new engine in Sochi, but crashed out in Q1 and was due to start at the back of the grid anyway.
Red Bull have introduced a slew of new engine parts to the Thai driver's pool, but the change of floor will necessitate his pit-lane start as it is a different specification to the one he had previously used.
Albon started the Chinese GP from the pit-lane earlier this year, and went on to produce a spectacular drive to take the final point-paying place.
