The Marussia Formula One team says it will run only one car at the inaugural Russian Grand Prix this weekend as a sign of respect for its injured driver Jules Bianchi.

Bianchi suffered a severe head injury at last Sunday's Japanese Grand Prix Suzuka and remains in a critical condition in a hospital in Japan. His car rammed into a crane picking up another car that had skidded off the course in wet conditions.

Marussia says that fielding a single car is "the appropriate course of action under the difficult circumstances of the weekend."

Reserve driver reserve Alexander Rossi is in Sochi but will not race. Max Chilton will drive the one car used.
