Marussia has announced it will only run one car during this weekend's Russian Grand Prix out of respect for Jules Bianchi.

With Bianchi seriously injured in the Japanese Grand Prix five days ago, Marussia was undecided on whether it would compete at all in Sochi. Having named Alexander Rossi alongside Max Chilton on the FIA entry list - allowing the team to keep all options open - it has now decided it will only field Chilton this weekend.

"The Team feels strongly that fielding a single car, that of driver number 4, Max Chilton, is the appropriate course of action under the difficult circumstances of the weekend," Marussia said in a statement.

Chilton said he was prepared for a difficult weekend having been left "devastated" by Bianchi's accident.

"I don't know how to put into words how truly devastated I am by what has happened to Jules," Chilton said. "The support from the F1 family has been incredible and all we can do is be there to support Jules' family at this difficult time. It is going to be a very emotional weekend for the whole Team, but we will try to get through it and keep praying for Jules."

Marussia has a complete car assembled on Bianchi's side of the garage, carrying his race number and #JB17 stickers, with Chilton's car also displaying the same tribute.
