Grosjean sported a bandage on his arm after his trip to the medical centre, but declared himself fit.

"I'm good," he said. "I won't be able to run a marathon right now but I'm very glad for Bell helmets and a HANS device and TecPro barriers.

"When I saw it coming I knew it was going to be a good hit. I released [my hands from] the steering wheel, kept my muscles strong and waited for it to be over.

"It's not the best feeling in the world but I'm very happy that the technology in Formula 1 is so good at the minute that you can have a big shunt and be able to speak about it.

"I feel a bit bad for the guys, because there's going to be a lot of work on the car, and we'll investigate what happened."

Grosjean said his early pitstop, to fix the front wing, was unconnected to the later accident, saying that the Force India of Sergio Perez moved across on him to avoid the second-corner crash and clipped him.

"I don't think it was related to that," he said. "We just lost the rear into a very high-speed corner. We need to see if it was my fault or something didn't work as expected."
