Three-time Formula 1 world champion Niki Lauda has undergone a lung transplant.
The 69-year-old had the surgery at Vienna General Hospital after initial reports claimed he'd be admitted for severe influenza.
According to the hospital, the transplant was necessary “because of a severe lung condition,” though it added in a brief statement that “the transplant was carried out successfully.”
The Austrian, who is now a non-executive director at Mercedes, missed the German and Hungarian Grands Prix as a result of the illness and resulting surgery.
It's not the first time Lauda has gone under the knife, having had kidney transplants in 1997 and 2005.
