AFP - Carlos Sainz has been given the all-clear to race in today's Russian Grand Prix, just a day after being hospitalised after crashing during practice.

The 21-year-old Spaniard was airlifted to a nearby hospital after he lost control of his Toro Rosso on the approach to the fastest section of the circuit.

Sainz collided into the near-side wall, destroying the front left of his car, before careering head-on into the tyre barrier at Turn 13.

He was expected to stay in hospital overnight, but he was released late on Saturday evening.

Early on Sunday morning he was given the green light by the FIA, the sport's governing body, to race.

The FIA said in a statement: "In accordance with normal procedures, Scuderia Toro Rosso driver Carlos Sainz was this morning examined by the FIA medical delegate and chief medical officer at the Sochi Circuit medical centre.

"Following this examination, the driver has been declared fit to race in today's Russian Grand Prix."
