Red Bull's Sebastian Vettel says he's fighting fit for home GP

Sebastian Vettel has confirmed he will be fighting fit for his home grand prix this weekend after suffering a leg injury earlier in the week.

The problem forced Vettel to pull out of a charity football match last night in Wiesbaden involving Formula One drivers and German entertainment stars.

"I fell down when I was running," explained Vettel.

"Nothing special but I had a bit of a hyper-extension of the muscle on the leg, nothing big. I can walk, it's not a disaster.

"But to play football would probably have been a bit too risky, so that's why I had to cancel.
