Massa Ready to Race at Indianapolis

Brazilian Felipe Massa has been cleared to race in Sunday's US Formula One Grand Prix after a heavy crash in Canada at the weekend.

"The medical checks in the hospital after my accident in the closing stages of the Canadian Grand Prix have proven that I was lucky enough to escape from it without injuries," the Sauber driver said in a team statement on Tuesday.

"I'm okay and ready to race next weekend."

Sunday's event, marking the midpoint of the 18-race Championship, will be Massa's first experience of the Brickyard circuit at Indianapolis. The Brazilian missed the 2002 race after being replaced by Germany's Heinz-Harald Frentzen and sat out last season as a Ferrari test driver.

"I have talked the layout over with the team, of course, and I am familiar with it from television footage," said Massa.

"The best way to learn a circuit, for me, is to go round it on a scooter, but in any case I learn them pretty quickly and it should only take me half a dozen laps to familiarise myself."
