McLaren-Mercedes have confirmed that Lewis Hamilton has had a 'precautionary' CT scan following his high-speed crash in qualifying for the European Grand Prix at the Nurburgring.

Hamilton went off in Q3 at turn eight and crashed into the tyre barriers with considerable force.

Team boss, Ron Dennis meanwhile has reiterated that the incident was due to a problem with the front right wheel nut, which was apparently not tightened properly.

"The main thing is that Lewis is absolutely fine with no injuries and no broken bones. He has been taken to hospital for a precautionary CT scan and we will know later today if he is able to race tomorrow," said Dennis.

"The accident was due to either a faulty air regulator or wheelgun causing the wheel nut on his right front wheel not to be tightened properly."

Dennis also added that they will conduct a through enquiry to discover why the issue occurred: "The team is undertaking a full investigation to understand how this could have happened," he continued.

Mercedes boss, Norbert Haug, like Dennis and the whole Woking-based squad - and indeed the rest of Formula 1, was relieved to see Lewis escape unharmed.

"The most important news of today is that Lewis is OK and he is now in hospital for a precautionary CT scan. The accident was not his fault," Haug summed-up.
