Alonso concussed in F1 crash
Fernando Alonso suffered concussion in a crash during Formula One pre-season testing.
The driver was a irlifted by helicopter to hospital after his McLaren went off the track and collided with a wall at the Barcelona-Catalunya circuit in Spain.
McLaren said the two-time former world champion was "conscious and able to speak" while receiving first aid at the circuit's medical centre, but he was taken to hospital for "precautionary checks".
After several hours of tests and observation, the team later added that Alonso was "uninjured" but had suffered concussion in the accident.
Team director Eric Boullier said: "Fernando's accident was just one of those things that happens in testing.
"Fortunately, he's fine, but was concussed during the accident, which therefore required an overnight stay in hospital as a precaution. That's normal practice after a concussion."
The Spaniard crashed after completing 20 laps. The accident occurred at turn three, when Alonso went off course and the right-hand side of his car hit the wall.
Neither the team nor track officials have reported the cause of the crash. Mr Boullier said the car was not badly damaged.
Alonso, 33, rejoined McLaren this season after a disappointing fifth and final campaign with Ferrari. He won back-to-back world titles with Renault in 2005 and 2006 before spending one season at McLaren in 2007.
Alonso has 32 career grand prix victories, the last of which came at Montmelo in 2013.
Testing resumed at the track after a slight delay following the lunch break.
Fellow Spaniard Carlos Sainz also saw his Toro Rosso go into the wall at turn three, but he emerged unscathed.
