A cameraman has been hospitalised after being hit by a wheel that came off Australian Mark Webber's Red Bull car at the German Grand Prix.

The wheel flew off the right rear axle of Webber's car during a pit stop after eight laps of the grand prix.

It bounced through two garages and hit the cameraman, Paul Allen, in the back.

He was treated immediately by medical staff in the pit lane before being moved to the circuit medical centre.

The sport's governing body, the FIA, says the British cameraman was then taken to Koblenz Hospital by helicopter, where he'll stay under observation.

Webber, who had been racing in second place, rejoined the race at the back of the field and eventually finished seventh.

Team mate Sebastian Vettel won his home race for the first time in his career, extending his Championship lead to 34 points.

Kimi Raikkonen was second, while his Lotus teammate Romain Grosjean finished third.
