At a test held at the Autodromo Nazionale Monza, Schumacher suffered a high-speed accident where he sustained a concussion. He was taken for a precautionary check at the circuit's medical centre before he was transferred to San Rafaele hospital. Although he had participated in the event's first qualifying session, Schumacher decided to withdraw and his place was taken by Williams test driver Marc Gené. He returned for the United States Grand Prix where he retired having suffered an accident resulting from his car sliding on a wet track surface. At the season finale in Japan, Schumacher finished 12th despite spinning his car three times. He finished the season fifth in the Drivers' Championship, with 58 points, and helped Williams clinch second in the Constructors' Championship.
