F1: Marussia asks for patience over Bianchi news

The Marussia Formula 1 team has asked for patience over updates about Jules Bianchi's condition after his Japanese Grand Prix crash.

Bianchi underwent surgery in Mie General Medical Center in Yokkaichi on Sunday, having sustained

a severe head injury

when he went off and hit a tractor that was recovering Adrian Sutil's crashed Sauber.

No further information regarding Bianchi's condition has been issued beyond the FIA's press office statement that Bianchi is in "critical but stable condition" after being moved moved to intensive care after the operation. Britain's Sky Sports reported that Bianchi is not breathing unaided, and that Professor Gerard Saillant – one of the world's leading orthopedic surgeons who oversaw the initial treatment of Michael Schumacher following the skiing accident that left him with severe head injuries – would arrive at the hospital tomorrow.

A statement from Marussia said, "With regard to the communication of information regarding Jules' medical condition, we will respect, and be guided by, the wishes of the Bianchi family. Together with Jules' care, they will remain our highest priority.

"Therefore, we would ask for patience and understanding with regard to further medical updates, which will be communicated in conjunction with the Mie General Medical Center in Yokkaichi, where Jules is being treated, when they feel it is appropriate."

Members of both the Marussia team and Ferrari – which has supported Bianchi's career through its driver academy program – remain at the hospital.
