Toyota wants to wait until later this morning to officially rule Timo Glock out of action for the Japanese Grand Prix, even though his injuries make it highly unlikely he can start.
Glock crashed heavily into the barriers on the exit of the final corner at Suzuka during qualifying on Saturday, and had to be taken to hospital for a cut on his left leg.
The wound required 14 stitches and, although Glock returned to the track on Sunday morning with a bandage around his leg, the injury makes him a serious doubt for the race.
Although few are expecting him to be fit enough to take part, a Toyota spokesman said the team would hold off for a while before making a final decision.
Toyota is already believed to have given up on a push to get reserve driver Kamui Kobayashi into the race under force majeure, as the Japanese cannot be given an automatic way in as he did not take part in third practice on Saturday.
