Fernando Alonso has been airlifted to hospital for further checks after crashing his McLaren-Honda during Barcelona Formula 1 testing.
The two-time F1 world champion went off on the exit of Turn 3 late in the Sunday morning session, and hit the wall on the inside of the circuit.
He was reported to be conscious and talking, but was taken to the medical centre by ambulance and then transferred to hospital by helicopter for further evaluation.
The accident came on Alonso's 21st lap of the day and while he was fifth in the standings.
McLaren had missed the opening hours of the test as Honda configured its engine following the overnight arrival of the re-engineered MGU-K seal intended to resolve its problems from earlier this week.
Alonso was only scheduled to drive for the morning before handing over to team-mate Jenson Button, as McLaren tried to equalise its drivers' mileage to get maximum feedback following another disrupted week of running.
