Further to the statement issued by Lucky Strike B·A·R Honda earlier this morning, the team can confirm that medical tests performed on Takuma Sato have concluded that his fever is symptomatic of a viral infection. Takuma is running a temperature and will now spend the rest of the weekend resting.

Takuma Sato: "I am obviously extremely disappointed that I have had to retire from the Malaysian Grand Prix - a race that I have prepared extremely hard for. Having discussed my condition with the medical staff and the team, I accept their advice that it is not sensible for me to take part in such a physically demanding race. I would like to take this opportunity to wish my team-mate Anthony Davidson well as he steps in for me for the rest of the weekend. I have now been advised to get plenty of rest and look forward to getting well again in time to be back in the car in Bahrain."

Anthony Davidson: "First of all I would like to wish Taku a speedy recovery. He is obviously very frustrated that he has had to retire from the race. Despite the circumstances, I am very much looking forward to making my race debut for B·A·R Honda here at Sepang. Malaysia is an extremely tough race for the regular drivers, so I know tomorrow will be a big challenge for me. However, my third driver role means I have to be prepared for times like these and I feel fit enough and mentally prepared to take over in the car. I have completed a lot of laps in free practice this morning and am happy with my times and the car balance, so I have a good starting point and will give it everything I've got for the team tomorrow."

Nick Fry, Chief Executive Officer: "Switching drivers at this point in the weekend is obviously far from ideal, but Taku's condition makes this the only sensible course of action. We are disappointed for him and hope he recovers well. Nonetheless, we are extremely fortunate to have Anthony Davidson on stand-by. He takes his role as third driver very seriously and is always race-fit and prepared for times such as this. It will be a tough challenge for him in these hot and humid conditions, but he has made a very good start to his race preparation and I know he will do an admirable job for us tomorrow."
