Marussia has yet to take a decision on whether or not it will run two cars in the Russian Grand Prix in the wake of Jules Bianchi's accident.

Bianchi remains in a critical but stable condition in hospital in Japan following his accident at Suzuka, where team principal John Booth has remained.

On the official entry list - released at 4pm by the FIA - reserve driver Alexander Rossi is named as a Marussia entry alongside Max Chilton, but no decision has yet been made on whether either car will race. Marussia was required to enter two cars to keep all options open, but could yet withdraw one or both.

Marussia says it will make a call on Friday morning as to how it proceeds, with the wishes of Bianchi's family central to its decision.
