Glock confident he will be fit for Brazil

The 27-year-old German sustained a deep cut in the back of his lower left leg, and was flown to hospital following his accident on the exit of the chicane during Q2.

And while Toyota initially hoped Glock would be fit enough to race in Japan, it has been decided that he should wait a fortnight before driving the car again.

"It should be quite easy for Brazil," he explained on Sunday morning, having returned to the circuit. "The problem at the moment is that I don't have pain when I put pressure on the leg.

"It is [more] the cut that does not give me the flexibility I need, and I think in two or three days it already should be a big step.

"Already from yesterday, I could not walk. Today I can walk. So in two or three days it should be much better, and in 10 days it should be okay. So Brazil should not be a problem.

"The cut is exactly across the back of my leg, behind the knee," he added. "It is six centimetres long. It was across the leg, which is the main problem, as it was quite open. It is also quite deep, so overall I am lucky that there was no damage to muscles or ligaments. They just closed it with 14 stitches and that is it.

"At the end of the day we tried everything overnight, in terms of physiotherapy to get it more flexible, but the problem is that I cannot just stretch it completely due to the cut and the stitches.

"In the end we worked until 2am tonight, and my physio did quite a nice job. But in the end, it is not possible to drive."

Glock admitted that the accident was caused by his own mistake and dismissed speculation that he may have encountered a problem with his steering wheel.

"That is wrong," he said. "Everything on the car was okay, 100 percent, unfortunately it was my mistake.

"It was just a mistake on my side. I had a bit of oversteer out of the last chicane and tried to take as much speed as possible out of the last corner. I opened the steering wheel, because I saw I was on a good time for Q2, and I just opened the steering wheel and at the last moment tried to turn back again.

"Then I misjudged around 50 centimetres - I thought I was half a metre to the right, but I wasn't. Then I just touched the grass slightly with the front left wheel and then the car just took off and I had no chance."
