Marussia driver Jules Bianchi is out of surgery and breathing on his own after suffering a severe head injury in a crash at the Japanese Grand Prix.
Bianchi, 25, hit a recovery vehicle and the rain-affected race in Suzuka was stopped early after 44 laps.
Governing body the FIA said he was unconscious as he was taken to hospital following the crash and was operated on before being moved to intensive care.
Bianchi lost control at Suzuka where an earlier incident had occurred.
In wet conditions, Sauber driver Adrian Sutil firstly spun and hit the tyre barrier as rain intensified in the latter stages of the race.
While recovery vehicles were lifting Sutil's car, Bianchi lost control of his car, travelled across the run-off area and hit the back of the tractor.
