Ex-F1 driver: 'Alonso took a 600W hit'

ROME, Italy - Officially, a gust of wind blew Fernando Alonso off the track on February 22, resulting in a concussion that has sidelined him for the 2015 Australian GP in Melbourne on March 15, claims McLaren.

Unofficially, rumours and doubt are still running wild.

F1 broadcaster Sky Italia claims the Alonso confided to close friends and family that he suffered a "major shock in his spine" before losing control of his McLaren-Honda and striking the wall at the Catalunya track in Spain.
