Toyota has confirmed that Timo Glock will not take part in the Japanese Grand Prix after his qualifying accident at Suzuka on Saturday.

The German was among a rash of drivers to go off during the hour-long timed session, uniquely making heavy contact with the barriers at the final turn. His extrication from the cockpit required a red flag while medoical teams did their work, and he was then flown to a local hospital for assessment after suffering what the team described as the time as a 'leg wound'.

Subsequent reports from Yokkaichi revealed that Glock - who missed the whole of Friday's opening day with a high fever - has sustained a 5cm cut to his lower left leg and was reporting back pain, although x-rays have confirmed there is no damage to that area.

With his fitness in doubt, and in order to ensure that he is fully fit for the Brazilian Grand Prix in two weeks' time, the former GP2 Series champion has again been advised to rest, and will miss the Japanese round, redcuing the 'home team' to a single entry, for front row starter Jarno Trulli.

"Together with my physio, I tried everything to be fit for the grand prix but, in the end, it is not possible for me to race," Glock confirmed, "We tried to get the fluid out of the leg and I can walk a bit better, but this morning we had to realise that it's not going to work - the cut is too big, and it's just not possible to drive."

"It is a pity to miss Toyota's home race and I'm annoyed that this has happened. I want to say thanks to my car crew because they worked all night to fix the damage and get it ready for the race. They did a great job but, unfortunately, I can't race. However, I am sure I will be back in Brazil."

Toyota applied for permission to reinstall official reserve Kamui Kobayashi alongside Trulli, the Japanese rookie having completed both Friday practice sessions in Glock's absence, but the bid was rejected by race stewards due to the regulation which requires a driver to participate in at least one session on day two of the event.

Glock admitted that the accident had been his fault, rather than the result of a problem with his car.

"Mechnically, it was not a problem, nothing went wrong," he confirmed, "I just made a mistake, misjudged the corner and oversteered out of the chicane. I tried to let the car go to take as much speed as possible out of the corner.

"You cannot really see the corner and, from my side, I was sure I was 50 centimetres to a metre to the right. Then, suddenly, I saw that was not going to work out and tried to steer back."
