3000 series. Ralph Firman suffered injuries as a result of a crash during practice in Hungary. He was replaced by Zsolt Baumgartner for two races before returning to finish the season for Jordan. Baumgartner, another driver who had been competing in the International Formula 3000 series, was the first Hungarian driver to race in Formula One. Ralf Schumacher was unable to race in Italy, due to concussion. He was replaced at Williams by Marc Gené, the team's test driver, for that particular race, before returning for the following Grand Prix. After a string of disappointing results in 2003, Jacques Villeneuve elected to end his season one race early, and was replaced at BAR by test driver Takuma Sato for the Japanese Grand Prix. Villeneuve would later drive for Renault in 2004 as a replacement driver, and sign a multi-year contract at Sauber for 2005 (though he was replaced in 2006).
